Product Description
12 point bolts have an alternative head design than standard hex socket cap bolts. The twelve point design permits greater torque to be applied to the screw which eliminates rounding out of the hex socket that can occur with fasteners of this type. U-Bolt-It recommends 12 point flange bolts for aircraft, mining, transportation, and agriculture manufacturing applications as well as diesel engine and transmission.
12 point flange bolt, also called Ferry Cap Bolt because of the 12-point head and flanged bearing surface. The large gripping surface offers more torque and tighter wrenching by hand power. They can be installed and removed with a standard 12-point socket or pneumatic wrench.
