ISO 4032 hexagon nut, also known as hexagon nut, has 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. For machanical properties, like proof loading, it is more higher than din 934. specialy requirements on grade 8 hex nuts, produced by high level raw material grade, and do heat treatment necessary.
iso 4032 Product Details
ISO 4032 Hexagon 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, coarse thread is used if there is no special requirement.
ISO 4032 hexagon 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 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.
