Hex nut DIN 934
Hex nuts DIN 934 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. 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. DIN 934 is a size standard for nuts. It is the first standard in Germany. If you want to test whether the mechanical properties of the nut are qualified, you must consult the DIN 267-4 standard. It specifies the detection method and Detection data, in this standard, it includes six levels of 4, 5, 6, 8, 10, 12. The proof loading of the nuts is constant, respectively 400MPa, 500MPa, 600MPa, 800MPa, 1000MPa, 1200MPa.DIN 934 real class 8 and false class 8
We believe that DIN 934 does not correspond to the so-called “true” level 8 and “false” level 8, but it is just a different name for the standard. In the new standard, the size of the opposite side has not changed except for the changes of M10, M12, M14, and M22; however, the thickness of the nut has become thicker, so the DIN 934 size standard, EN 20898-2 mechanical properties It is unscientific to test nuts according to the standard, and it may not always be required. In summary, DIN 934 can only correspond to DIN 267-4; DIN EN ISO 4032 can only correspond to EN 20898-2. According to the different standards, we have compiled the mechanical properties and dimensional standards in the two standards of DIN 934 |8| and ISO 4032 8 into a comparison table for everyone to learn more about the true meaning of DIN 934 |8| and ISO 4032 8.
