DIN 934 hex nuts
DIN934 hex nuts, also called hexagon nut, has a metric coarse thread and fine thread. it is equivalent to ISO4032 hex nuts, DIN EN 24032 hex nuts. This hex nuts is commonly used in construction projects. It’s also commonly used in vehicles. The most common use in conjunction with a bolts, studs and screws.
The hexagon nuts grades are 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.
Commonly used material: Brass, carbon steel, A1, A2, A4, 303, 304, 316 stainless steel, aluminum, plastic…
DIN934 Nuts Details
Hex nuts DIN 934 are often used with bolts, studs and screws. It’s shows 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.
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.
