What is a Tap Bolt?

Tap bolts are fully threaded hex bolts. Unlike tapping screws tap bolts do not form their own mating internal threads. They are instead designed to be inserted through holes in assembled parts and tightened by torquing a nut or mated with an internally threaded (tapped) hole and tightened by torquing the bolt’s head just like their hex bolt counterparts. Aside from the vehicle repair industry they are used in a variety of applications like attaching motors to machinery and in combination with pulleys to adjust belt tension. They have hex heads along with an under head washer bearing surface. Hex tap bolts, fully threaded hex bolts fully threaded hex cap screws.

Threads are standard right hand and often Unified inch coarse series. Tap bolts are always fully threaded, which allows them to accommodate a large material thickness range. The point is chambered or rounded to protect the first thread from damage and to facilitate entry into an internally threaded part. Typical sizes range from 1/4″ to 3/4″ in diameter while lengths span from about 3/4″ to 6″. Measure length from the under head washer bearing surface to the threaded end of the bolt.
