Twelve Point Flange bolts a/k/a 12-Point Flange Head Cap screws coarse thread are a fastener with a twelve (12) point head (similar to the head dimensions of a socket head cap screw) and has a flat or indented top surface, twenty-four (24) flat sides, and a larger bearing area circular collar at the bottom of the head and the flat bearing surface.  The 12-point head design assists with tightening 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.  12 Point Flange bolts or twelve (12) point flange head cap screws are sometimes referred to as “Double Hexagon Head”.
