Product Advantages
Advantages of Hex Socket Cap Bolts
1. The head shape of the Allen cap screw can bear a larger load.
2. Since the head needs to be embedded in the parts, the connection strength of the hex socket cap bolts is greater.
3. Compared with ordinary bolts, DIN 912 Allen bolts can achieve higher torque and clamping force.
4. Under the condition of the same clamping force, fewer hexagon socket bolts are used.
5. Fewer drilling and tapping into the mounting surface, saving time and reducing potential damage to components.
6. The use of Allen bolt DIN 912 can reduce the weight of the finished product.
7. AYA will provide you with the most suitable fastening solution according to the actual situation in your area.
