12 Point Flange Bolt

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. 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.
