Types of custom fasteners include the following main types:
Bolt: Bolts are cylindrical fasteners with threads, usually used in conjunction with nuts, and tightening is achieved by rotating the nuts. Bolts are widely used in various mechanical equipment and structures, and are important components for connecting and fixing parts.
Nut: Nuts are parts used in conjunction with bolts, and have threaded holes inside that match the bolt threads. By rotating the nut, the bolt can be tightened or loosened.
Screw: Screws have external threads and are usually screwed directly into the threaded holes of the connected parts without the need for nuts. Screws can play both a tightening and a positioning role during the connection process.
Studs: Studs are fasteners with threads on both ends, usually used to connect two thicker parts. The fastening effect of studs is stable and suitable for occasions with large tensile forces.
Washers: Washers are used to increase the contact area between connecting parts, prevent loosening, and reduce wear. Washers are usually used with fasteners such as bolts and nuts.
Self-tapping screws: Self-tapping screws have special threads that can directly tap threaded holes on the connected parts and achieve fastening. Self-tapping screws are widely used in the connection of thin plate materials.
Rivets: Rivets connect two or more parts together by riveting, and the connecting parts have high strength and stability.
Pin: Pins are used to connect and position two parts. They usually have a small diameter and a long length and are suitable for occasions that require precise positioning.
Retaining ring: Retaining rings are used to prevent axial movement of shafts or parts on shafts. They are usually installed on the end faces of shafts or holes, and limit the axial movement of shafts or parts on shafts through their elasticity or rigidity.
Wood screws: Wood screws are specially used to connect wood. They have shallow threads, are easy to screw into wood, and have good fastening effects.
Studs: Studs are high-strength, fast-welding fasteners suitable for a variety of steel structure buildings and industrial manufacturing fields. Welding nails are fixed to a part or component through welding technology, so as to be firmly connected and assembled with other parts later.
Assembly and joint pair: An assembly is formed by combining multiple parts, while a joint pair is a combination of screws or bolts and washers. These assemblies and joint pairs are used for specific connection and fastening needs.
