Bolts, nuts, and washers, what do they have in common? These three types of fasteners are all under the category of non-permanent or temporary fasteners. They are removable mechanical parts that share a common function to fasten\/affix, join, and hold materials together.<\/span><\/p>

Bolts and nuts<\/b><\/a> are designed to match each other in critical applications, nuts are inserted through the threads of bolts to tighten an assembly. While the <\/span>washer <\/b>is an enhancing device inserted between a bolt and a nut to help in distributing the load over the surface and materials.\u00a0<\/span><\/p>

    Usually feature a hexagonal head but can be also modified in different head types and head drives. Bolts have cylindrical male threads in their shank (body) that have full or partial threading. Unlike screws, bolts have an untapered body which makes them unable to tap into the surface of the application, hence the need to pre-drilling a pilot hole for its installation.<\/span><\/p>

    \u0645\u0633\u0627\u0645\u064a\u0631 \u0627\u0644\u062a\u062b\u0628\u064a\u062a<\/b> are used in construction for joining materials into a concrete surface or base of steel poles.<\/span><\/p>

    Blind Bolts allow the fastening of materials that have a blind spot or can only be reached from one side.\u00a0<\/span><\/p>

    \u0645\u0633\u0627\u0645\u064a\u0631 \u0627\u0644\u0646\u0642\u0644<\/b> are mainly applied in wood base fastening or wood-to-metal applications.<\/span><\/p>

    \u0645\u0633\u0627\u0645\u064a\u0631 \u0634\u0641\u0629<\/b> consist of a flange head that acts like a washer, commonly used for areas of automotive, piping, plumbing, etc.<\/span><\/p>

    Socket Head bolts<\/b> have internal threading to suit the application in confined spaces like machine assembly<\/span><\/p>

      \"washer<\/p>

      Unlike the common threaded fasteners, nuts largely differ in physicality. They are usually in form of circular, hexagonal, and square prisms with internal threading. Nuts cannot function alone and thus require a mating fastener with male threads like bolts or screws. This mechanical device is used for enhancing the grip and hold of bolts into the materials.<\/span><\/p>

      \u0635\u0648\u0627\u0645\u064a\u0644 \u0627\u0644\u0634\u0641\u0629<\/b> have the same feature as flange bolts. Its wide flange distributes the pressure all over the materials.<\/span><\/p>

      \u0635\u0648\u0627\u0645\u064a\u0644 \u0633\u062f\u0627\u0633\u064a\u0629<\/b> are six-sided in the form used in pairing hex bolts or other compatible types of bolts.<\/span><\/p>

      Lock nuts<\/b> are known for their self-locking ability that prevents the loosening of bolts due to vibrations.<\/span><\/p>

      Slotted nuts<\/b> offer an efficient fastening and locking application. They can be used in bolts and screws along with a cotter pin.<\/span><\/p>

        \"Figure<\/p>

        An easy distinguishing feature of washers is their flat disc form with an opening hole in their center. Its significant function is to evenly distribute the load that fasteners receive to add an efficient level of durability to the assembly.\u00a0<\/span><\/p>

        A Spring washer<\/b> acts as a spring that receives the force load in the assembly and distributes it around the materials involved.<\/span><\/p>

        A plain washer<\/b> refers to the standard or plain form of the washer.<\/span><\/p>

        What Are the Markings in Bolts?<\/span><\/h2>

        The particular markings found in the head of bolts and nuts are a distinct feature that characterizes their manufacturing quality. Do you often see and wonder why there are numbers, letters, dashes, or an assortment of symbols in your fasteners? They identify the grades or standards of the bolts. A certain grade on fasteners also determines their capacity for strength, durability, etc. Some sizes of bolts that are small in diameter can lack the identification mark on the head. However, they are strictly manufactured to follow the standards.<\/span><\/p>

        Steel is a common type of material used in the production of fasteners. These are the following grades of steel;<\/span><\/p>
