High-strength hex bolts are the most widely used type of bolts. Class A and Class B high strength hex bolts are used for important assembly accuracy requirements and where large shocks, vibrations or loads are accepted. Class C high-strength hex bolts are used in places where the appearance is rough and the assembly accuracy is not high.
The thread of the high-strength hex bolt is generally a common thread of coarse teeth, and the ordinary threaded bolt of the fine tooth has good self-locking property, and is mainly used for a thin-walled part or a place with impact, vibration or alternating load. Generally, the bolts are made of partial threads, and the full thread bolts are mainly used in places where longer threads are required. Perforated bolts are used where bolts are required.
