Fasteners refer to two or more parts (or components) fastened and connected into a whole is a general term for a type of mechanical parts used. There are many functions of fasteners, so in all walks of life, you can basically understand fasteners. Everyone will know something about them. After all, they should have been exposed to them in daily life, but you know what they are Are self-clinching fasteners ?

The diameter of a self-tightening nut is usually smaller or larger than a standard fastener of the same specification, and the difference is usually 1% to 6%. Self-tightening nut is one of them. Due to the difference in the pitch of the nut and the matched bolt, it does not require any auxiliary materials or additional matching parts, the structure is simple, the use is convenient, the operability is strong, and the anti-loosening effect is very good. A self-tightening fastening Parts, can be widely used across railways, railways, tunnels, turnouts, automobiles, machinery and occasions that need to be in vibration for a long time and need to be secured and secured against loosening.

Of course, in addition to custom fasteners that can achieve this effect, custom-made fasteners can also achieve this effect, and the volume of space that custom-made fasteners can expand and contract freely will still have certain constraints.
