Material of Locking Nut

Locking nut is a kind of nut widely used in machinery and other industries. Its working principle is self-locking by friction between nut and bolt. But the reliability of this self-locking will be reduced in dynamic load. On some important occasions, we will take some measures to prevent loosening to ensure the reliability of nut [...]

Embedded Nuts

Embedded nuts are copper nuts made of various embossed wires. Embedded nuts we come into contact with are processed by precision automatic lathes. The main operation mode of embedded knurled copper nuts is injection moulding and embedding after heating. If the melting point of PA/NYLOY/PET is above 200 C, the temperature of the embedded nut [...]

Locking Nuts

The purpose of locking nuts is to lock open wire external joints or other pipe fittings. The working principle of nuts is self-locking by friction between nuts and bolts. But the reliability of this self-locking will be reduced in dynamic load. On some important occasions, we will take some measures to prevent loosening to ensure [...]

Anti-loosening Nut

The anti-loosening nut is composed of two parts, each part has a staggered cam. Because the slope angle of the internal wedge design is larger than the angle of the nut of the bolt, the combination will bite tightly into a whole. When vibration occurs, the uplift part of the DISC-LOCK anti-loosening nut dislocates with [...]
