Introduction And Use Of Bolts

Introduction and use of bolts

Hex Bolts

Hex bolts are the most widely used type of bolts. Its grade A and grade B bolts are used for important occasions where assembly accuracy is required, and where large shocks, vibrations, or alternating loads are tolerated. Its C-grade bolts are used for occasions where the surface is relatively rough and assembly accuracy is not required. The threads on the bolts are generally ordinary threads. West Asian ordinary thread bolts have better self-locking properties and are mainly used on thin-walled parts or in situations where they are subjected to shock, vibration or alternating loads. General bolts are made of partial threads, and full-threaded bolts are mainly used for bolts with short nominal lengths and occasions requiring longer threads

Hex Flange Bolts

The head of the hexagonal flange bolt is composed of a hexagonal head and a flange surface. Its "support area to stress area ratio" is larger than that of ordinary hexagonal head bolts, so this kind of bolt can withstand higher pre-tightening force and prevent The loose performance is also good, so it is widely used in automobile engines, heavy machinery, and other products

Hexagon Head Hole, Slotted Bolts

When in use, the bolts can be locked by mechanical methods, and the anti-loosening is reliable

Hexagon head screw hole bolt

The cotter pin hole is made on the screw to pass through the wire hole, and mechanical loosening is adopted to prevent loosening reliably.
