12 Point Flange Screw

12-point flange screws, also commonly known as Ferry Cap Screws or 12-point flange head cap screws, feature a 12-point external drive design that allows for higher torque application compared to traditional hex heads, significantly reducing the risk of rounding the drive recess. The integrated flange provides a built-in bearing surface, eliminating the need for a separate washer and distributing clamping force evenly.
