Nuts are often used with bolts and screws. The results show that the self-locking ability and locking ability of the coarse hexagon nut are worse than that of the fine-tooth hexagon nut, but the locking force is greater than that of the fine-tooth hexagon nut; the fine-tooth hexagon nut has good locking performance, which is suitable for anti-vibration and easy to adjust the clearance, but the locking force is worse than that of the coarse hexagon nut, so it is suitable for the place where the clearance or torque should be adjusted. In general, the coarse thread is used if there is no special requirement.
Nut is widely used, and it is often used with bolts, studs, and screws to connect and fasten. Grade A (applicable to nominal thread diameter D ≤ 16 mm) and grade B (suitable for d > 16 mm) nuts are used in machines, equipment, or structures with small surface roughness and high precision requirements. It is characterized by a relatively large tightening force, which can be installed with a movable wrench, an open-ended wrench, or a spectacle wrench, all of which require a larger operating space.
