Product Details
Product Advantages
Advantages OF 12-POINT CAP SCREW
1. The 12-point bolt head design means that this screw can be tightened with a 12-point socket wrench which allows higher torques to be applied as compared to a standard internal hex drive socket head cap screw.
2. This feature, combined with the larger bearing area under the head of the flange design provides further benefits over a traditional hex head cap screw.
3. Use them for heavy-duty stamping applications as well as earth-moving machinery, such as bulldozers and excavators.
4. The head makes 12 points of contact with a wrench to handle more torque than a socket head or hex head screw.
5. The flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer.
6. To install, use a 12-point wrench that matches the head width of your screw.
