How do DIN 912 hexagon socket head bolts work?
- Threaded fastening: The thread of the bolt cooperates with the nut or threaded hole, and the two parts are fastened together by rotating the bolt.
- Hexagon drive: Insert the hexagonal hole of the bolt head with an hexagonal wrench, rotate the bolt, and apply torque to screw the bolt into the nut or threaded hole.
- Axial force and friction: When the bolt is tightened, the axial force generated by the thread presses the two connecting parts tightly together, and the friction further prevents them from sliding relative to each other.
- Anti-loosening mechanism: After tightening, the anti-loosening function is provided through friction and elastic deformation of the material. If a higher anti-loosening function is required, auxiliary methods such as anti-loosening washers or thread locking glue can also be used.
