Tap bolts, also known as hex head bolts, have comparable tolerances to hex head cap screws and are often times referred to as fully threaded cap screws. The hex bolt has a fully-threaded shank (threading from the point up to the head) and a chamfered point to facilitate mating with an internally threaded component. Used in a variety of industries including manufacturing, construction and automotive applications, the hex bolt has the tensile strength required for harsh or corrosive environments. Tap bolts are designed for use in drilled and tapped holes which are threaded full length.
