DIN934 Hex head nuts,Carbon Steel,Coarse Threaded ,Zinc Plated
Product Description:
Hexagonal nuts are used in conjunction with bolts and screws to connect and fasten parts. Among them, type 1 hexagonal nuts are most widely used. Class C nuts are used for machines, equipment or structures with rough surface and low precision requirements. Class A and B nuts are used for machines, equipment or structures with relatively smooth surface and high precision requirements. The thickness of type 2 hexagonal nut m is thicker. It is often used in occasions where assembly and disassembly are often required. The thickness of hexagonal thin nut m is thinner, which is mostly used when the surface space of the connecting parts is limited.
For hexagonal nuts, the commonly used standards are: GB52, GB6170, GB6172 and DIN934.
Ordinary outer hexagonal - widely used, characterized by a relatively large fastening force, the shortcoming is that there is sufficient operating space in the installation, installation can be used flexible wrench, open wrench or glasses wrench, the above wrench requires a lot of operating space.
The role of nuts is to screw bolts or screw together to play a fixed role, using high-speed cold heading machine forming, uniform thickness, smooth surface, even spacing, clear threads, durability, not easy to rust, not easy to appear brim.
