Machine Screw Nut Basics

Types and Sizes

You should learn about the main types and sizes before buying any machine screw nut. Each type has its own shape and job. Some common types are hex nuts, jam nuts, cap nuts, and flange nuts. The table below shows what they do and where you use them:

Type of NutDescriçãoAplicativos comuns

NozesThese are thin nuts that lock another nut in place.They help keep bolts tight in machines, pipes, and cars.
PorcasThese nuts have a rounded top to cover threads.You see them in furniture, lights, and outdoor things like handrails.
Porcas FlangeadasThese nuts have a wide bottom for spreading pressure.People use them in cars, machines, planes, and furniture.

Machine screw nut sizes are measured by diameter and thread pitch. Some sizes are small like #2-56, and some are bigger like 1/2-13. You should look at the size chart from your supplier, such as Prince Fastener, to make sure you pick the right one.

Dica: Always check the thread size and type before you order a lot. This step helps you stop mistakes and waiting.

Usos comuns

People use machine screw nut products in many jobs. These nuts hold things together in machines, cars, and furniture. You also find them in electronics, building work, and fixing things at home. When you need to connect two pieces of metal or attach something to a surface, you often use a machine screw nut.

These nuts give strong and safe connections. They work with bolts and machine screws. You can find them in toolboxes, workshops, and factories. If you want to buy a lot, you need to know which type and size are best for your work. This helps you save time and money.

Key Factors for Bulk Buying

When you want to buy a lot of machine screw nuts, you should think about some important things. These things are material and grade, size and fit, and industry rules. If you pay attention to these, you will not make mistakes. Your project will go well.

Material and Grade

You need to check the material and grade before buying many nuts. The material tells you how well the nut fights rust and damage. For example, 316 stainless steel does not rust as fast as 18-8 (304) stainless steel. This is why people use it near the ocean or with chemicals. The grade shows how strong the nut is. Higher grades are stronger and good for tough jobs.

Aqui está uma tabela que lista common nut grades and what they are used for:

Nut GradeUso típicoProof Load (MPa)Matches Bolt Grades
Class 4Light-duty, low stress~225 MPa4.6 bolts
Class 5Medium-duty~310 MPa5.8 bolts
Class 6Construção geral~380 MPa6.8 bolts
Class 8Machinery, automotive~600 MPa8.8 bolts
Class 10Maquinário pesado~830 MPa10.9 bolts
Class 12High-stress applications~970 MPa12.9 bolts

Dica: Pick the right material and grade for your job. If you work in a tough place, choose nuts that do not rust easily. For big machines, use higher grades to stay safe.

Using the right grade and material helps you stop problems. Prince Fastener has many grades and materials, so you can find what you need.

Dimensionamento e compatibilidade

Getting the right size is very important when you buy a lot. If you pick the wrong size, things can break or fall apart. For example, if you use a weak nut where you need a strong one, the joint can come loose or break. This can cause things to fall or get damaged.

You should always match the nut size to the bolt and the job. Check the diameter and thread pitch. Some nuts have UNC or UNF threads, so make sure they fit your machine screws. Prince Fastener gives you size charts to help you choose.

  • Measure the bolt’s diameter and thread pitch.
  • Match the nut to the bolt’s grade.
  • Check that everything fits before you order a lot.

Observação: Do not use a weak nut for a strong job. This keeps your project safe and stops accidents.

Padrões industriais

Industry rules help you pick safe and good nuts. Rules like ISO and DIN tell you how nuts should look and work. If you follow these rules, your nuts will do their job right.

Here is a table of common rules for machine screw nuts:

Storage and Organization

Bolt Bins and Storage Solutions

You need a good way to keep your machine screw nuts safe. This helps you find them fast and not lose any. If you use the right storage, you will not waste time looking for parts. Many shops use bolt bins, bins on the wall, or cabinets with many drawers. Each one has its own good and bad points.

Storage SolutionPrósContrasMelhor para
Portable Parts OrganizersEasy to carry, cheap, stackable, clear lids help you see insideCan get heavy, hard to find the right case sometimesBeginners and workers who need hardware at different places
Wall-Mounted BinsEasy to see, you can change them, saves floor spaceGets dusty, needs wall space, can cost moreShops with big walls and people who need to grab things often
