DIN934 ISO 4032 Stainless Steel Hex Nut

DIN 934 hexagon nut, also known as hexagon nut, has a metric coarse thread and fine thread. The product grade is a and B. grade A is used for specification less than or equal to M16, and grade B is used for specification larger than M16.

Hex nuts DIN 934 is 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.

Hexagon nut DIN 934 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.
