A 12-point bolt offers the same bearing surface as a hex head cap screw or socket head screw of equivalent sizes. The external drive provides tighter wrenching with a larger gripping surface to offer more torque. Special dimension can be manufactured to meet your needs in inch or metric sizes.
Please note: 12-point bolts are generally made from alloy steels. However, they can be made from different materials based upon customer requirement.
