Prince fastener production process
Basic concepts of Prince Fastener screw production
1、Prince Fastener Manufacturing screw can be divided into: cold heading, hot machining (turning, milling, etc.)
2、Cold heading is the use of plastic metal, by using cold mechanical pressure or drawing, reaches the metal solid deformation of.
3、Hot upsetting is the material after heating and pressure processing make the shape of the material to meet the
designrequirements.
4、Prince Fastener Machining is a small batch of special or special bolts of the six corners of the head is turned into after the milling.
5、 Screw bolt thread: mechanical and manual threading, similar to die.
6、 Milling tail: generally completed by the end of the Prince Fastener cutting machine.
7、 The difference between cold and hot upset: cold heading bolts` surface are more beautiful, dozen red bolt surface oxide skindoes not look good; cold heading high production is efficiency; general Prince Fastener M24 bolts will need to play red;
Analysis of the causes of the phenomenon and the causes of the forming process
1、Eccentric: two red and improper installation and adjustment machine.
2、Minow: a poor installation and improper Prince Fastener adjustment machine at.
3、Head is not round: the choice of a die or a punch forming is not enough.
4、Play the mode of crack: crack or die R angle, so that the model is hit by the two collision.
5、Head double: bad punch.
6、Flash: a bad, punching molding is mainly between punch and die hole clearance is too large or too short by red bars.
7、Crack angle: the punch needle burst or two punch and punch is not heavy.
8、Head cracking: material, or a die using error (such as pan head Hexagon washer head of a die), and lubricating oil.
Analysis of adverse phenomena and causes of common rolling
1、Processing crack: tooth plate and adjust the Prince Fastener old machine.
2、Blunt tail: the machine is not properly adjusted, the tooth plate is too old.
3、Crooked tail: the control screw on the seat board seat is too tight.
4、Tail: tooth wear plate and improper adjustment machine.

Since it is self-forming or can be tapped to match its threads, it has a high loosening prevention ability in combination and can be loaded and unloaded. The small-shaped screws on its size, thread type, head type, tapping performance for engineering purposes, high tensile strength, single piece, and single-sided combination features are almost unlimited. Self-tapping nail material can be divided into two kinds: carbon steel and stainless steel, in which the carbon steel material to 1022 carbon steel is the main. Usually used in doors and windows, etc.
Its head is made at one end to increase the shape of the part formed by the bearing surface. For thread forming and thread cutting, self-tapping screws , flat-top countersunk head ( FlatCountersunk ), flat round countersunk head ( Oval Countersunk ), Pan head ( Pan ), Hex and Hex washer head ( Hex and Hex Washer Head ) is the most important, these five head types account for almost 90% of all self-tapping screws, The use of self-tapping screws should first consider this. Another five other types of flat-top concave bearing surface ( Flat Undercut ), whole flat-top edge ( Flat Trim ), flat round concave bearing surface ( Oval Undercut ), flat round top edge ( Oval Trim ), and cylindrical head ( Gang Hill head Fillister ) for the relatively minor head type, while the incense top buried head.
Threaded rolled into self-tapping screws head type selection and the same above, the use of the main consideration mushroom head ( Truss ), round head ( Round ) and 100 degrees flat top buried head for the new design is not taken, cover its function can be replaced by another head type, the disk head can replace the mushroom head, and round head, 82 degrees flat top buried head can replace the 100 degrees flat for the flat top, flat dome, disk head, hexagonal head and hexagonal washer head five kinds.
2,What are Self-tapping screws made of?
Self-tapping screws are mostly used for the connection between thin metal plates. When connecting, first make a threaded bottom hole for the connected piece, and then screw the self-tapping screw into the threaded bottom hole of the connected piece. Since the thread surface of the self-tapping screw has high hardness (≥45HRC), the internal thread can be tapped in the threaded bottom hole of the connected piece to form a connection. The aluminum profile itself is softer than steel, so generally self-tapping screws that meet the national standard can tap the aluminum profile. It is recommended to punch the bottom hole at the required position first.
So Normally the self-tapping screw made of stainless steel or carbon steel, titanium, aluminum, brass materials
3,What are the uses of Self Tapping Screws?
Self-tapping screws are mostly used for the connection between thin metal plates (steel plates, saw plates, etc.). When connecting, first make a threaded bottom hole for the connected piece, and then screw the self-tapping screw into the threaded bottom hole of the connected piece. Since the thread table of the self-tapping screw has high hardness (≥HR5), the internal thread can be tapped in the threaded bottom hole of the connected piece to form a connection.
Self-tapping screws are also mostly used for the connection between thin metal plates. The thread is an ordinary thread with an arc-shaped triangular section, and the thread surface also has high hardness, so when connecting, the self-tapping screw can also tap the inner thread in the threaded bottom hole of the connected piece to form a connection. This kind of screw is characterized by low screw-in torque and high locking performance, and has better working performance than ordinary self-tapping screws.
4,Can self tapping screw be used instead of machine screws?
When installing and disassembling self-tapping screws, slotted self-tapping screws need a flat-blade screwdriver, cross-recessed self-tapping screws need a cross-shaped screwdriver, hexagon socket self-tapping screws need a socket wrench, hexagon head self-tapping screws Tapping screws require a flat wrench, a Torx wrench, a socket wrench or an adjustable wrench.
Self-tapping screws are used for non-metallic or softer metals without drilling low holes and tapping;
Self-tapping screws are pointed, so that they can be self-tapping; ordinary screws are flat-headed and have the same thickness.
Self-tapping screw means: the drilled hole is a chip-free tapping hole. The screw used is different from the general one. The head is pointed and the tooth spacing is relatively large. Going in, metals and plastics usually use this method.
Self-tapping screws are screws without nuts.
It can “tap-drill, squeeze, press” the corresponding thread on the consolidated material by its own thread to make them cooperate closely with each other.It can be used for below industries:
1.furniture industry 2.building industry3.toy industry 4.plastic case industry 5.auro industry 6.military industry 7.medical instruments industry 8.aerospace industry 9.shipbuilding industry 10.energy equipment industry 11.electronic industry 12.furniture industry 13.materials industry
5,What is Classification of self tapping screw?
I: The different heads can be divided into round head, flat head (i.e., hollow head), top pillar head, round top broadside head, large round head (i.e., large flat head), hexagonal cavity-bearing head, hexagonal cavity-bearing washi head, hexagonal head.
Round head self-tapping screw: It is the most common head type in the past.
Flat head self-tapping screw: A new design that can replace the round head and mushroom head, with a low head diameter and a high type of edge around the head’s periphery that indicates the drive’s characteristics for increased torque.
Head self-tapping screw: The standard flat round head has a smaller diameter than the round head but is taller due to the depth of the groove, and the smaller diameter increases the pressure on a small area, which can be tightly combined with the flange and the raised surface. They can be successfully used in internal drilling holes because they are punched in drilling molds to ensure concentration.
Domed broadside head self-tapping screws: Most commonly used in electrical appliances and recorders because of the undercutting of the head and the reduced wear on the wire components, providing a more attractive design type for the low and medium head types with their fuller bearing surface.
Large round head self-tapping screw: The oval top broadside head is a low profile, cleverly designed large-diameter head type. It can be used to cover sheet metal holes with large diameters when the combined tolerances of the additional roles allow. A flat head is also recommended as an alternative.
Hexagonal cavity head self-tapping screw: A joint with a wrench head height and a hexagonal head size. The hexagonal shape is entirely formed by cold forming in a counter-bored mold, and the top of the head has a distinctive depression.
Hexagonal cavity head self-tapping screw: Like the standard hexagonal cavity head, but with a cavity surface at the base of the skull to protect the assembly from wrench damage. Sometimes the function of the thing is more important than the appearance.
Hexagonal head self-tapping screw: This is a standard type of torque applied to the hexagonal head and has the feature of trimming sharp corners to close tolerances. It is recommended for general commercial use but can also be used for various standard patterns and thread diameters. However, it is more expensive than the available hexagon socket because of the second process required.
II: According to the groove type, there are four types of grooved head: one grooved head (also called slotted), cross grooved head, eleven composite grooved heads, and meter grooved head.
III: According to the standard can be divided into National Standard (GB), German Standard (DIN), American Standard (ANSI), British Standard (BS)
6,Self Tapping Screws Manufacturers in China:Are your self-tapping screws reliable?
As a professional self-tapping screw manufacturer, we guarantee that from the raw material to the finished products, we have to go through 8 inspection processes, and only after passing the inspection can we ship. To ensure the quality of self-tapping screws (Character) in customers’ is a qualified screw.
No matter what specifications of self-tapping screws fasteners, after the completion of production are required to do a series of tests, testing qualified (qualified) before shipment, then the regular size test, tolerance test, and appearance test, we also need to try what items? Self-tapping screws mechanical (machinery) performance test (test) projects include (bāo kuò) surface hardness test, carburization (shèn tàn) layer depth test, core degree test, microstructure test, screwing performance test, and damage (vandalism) torque test.
1, Surface hardness test (test).
Surface hardness using GB/T5030 specification Vickers hardness (HV0.3) test (test), surface hardness test should be on the plane and priority in the head. Non-standard screws are tools that use the physics and mathematics of the object’s beveled circular rotation and friction to tighten the apparatus mechanism progressively.
2, Carburizing (C) layer depth (metallographic test)
The carburization (C) layer depth test (test) is carried out on the measuring surface of the self-tapping thread at a point half the distance between the top of the tooth and the bottom of the tooth, except for self-tapping screws with specifications <ST3.9, in which case the test should be carried out on the base of the tooth. The depth of the carburization layer shall be calculated from the point where it exceeds 30 HV.
3. Hardness of core test.
Vickers core hardness (Hardness) test according to GB/T4340 and should have sufficient distance (distance) with the end of the self-tapping screw (there should be a complete thread diameter) of the cross-section of 1/2 radius (radius). Non-standard screws are tools that use the physics and mathematical principles of beveled circular rotation and friction of objects to tighten objects and mechanisms progressively.
4, Screwing performance test (test)
Self-tapping screws (screw) nail test piece (with or without coating) screwed into the test (test) plate until there is a complete thread entirely through the test plate; the test plate should be made of low carbon steel (Steel) with a carbon content of <0.23%, the hardness of 130-170hv (measured by GB/T5030 and GB/T4340) test plate thickness (thickness) degree and test aperture. thickness) degree and test aperture by the hole or punching and then drilling or reaming system. Precision screws are widely used in electronics, electrical, appliances, furniture, machinery, etc.
7,Is a self-tapping screw the same as a self-drilling screw?
Self-tapping screws are screws that are capable of tapping the threads into the material. Self-tapping screws can be used in various materials, including wood, metal, and brick. These screws cannot be drilled through metal and require a pilot hole to be pre-drilled before installation. The pilot hole is created by using a drill bit slightly smaller than the screw, and the screw’s threads strike the metal or wood as the screw is installed. This tapping action holds the material together. In addition, self-tapping screws can have many different types of tips, which help tap the threads into various substrates.
Self-drilling screws are sometimes named under the Tek®Screws brand. These screws can be identified by the point of the screw’s drill shape and are designed for various applications, such as fastening metal to metal and wood. In addition, self-drilling screws do not require pilot holes, reducing installation time and costs and the need for additional drilling. This other functionality and cost-saving features make self-drilling screws the clear choice for metal construction. Drill points are numbered 1 through 5, and the amount of steel that can be drilled increases as the numbered points increase. Typically, self-drilling screws are used for light rail applications, but the #5 drill point can dig through and hold 1/2 of the steel.
So self-drilling screws are also self-tapping screws, but all self-tapping screws are not self-drilling hammers. Custom Self-drilling screws do not require pilot holes, but they can be self-tapping. Self-tapping screws cannot drill through metal and require a pilot hole. These screws are not interchangeable, and mixing the two may cause a lot of trouble or cause failures in the field.
8,Self Tapping Screws Manufacturers in China:Have you exported your self tapping screws before?
