1/4-20 X 2 1/2 TAP BOLT A307 GRADE A

A tap bolt, also known as a fully threaded hex bolt or a tap screw, is a type of bolt that features threads along its entire length. Unlike standard bolts, which have a portion of their shaft unthreaded, tap bolts are threaded from the head to the tip, allowing them to be inserted into a threaded hole or nut for secure fastening.

Tap bolts are commonly used in applications where a fully threaded connection is required, providing consistent and reliable threading along the entire length of the bolt. They can be tightened using a wrench or socket on the hexagonal head. Tap bolts are often used in situations where a threaded hole is present, and the bolt is used to clamp or hold components together, providing a tight and secure connection.
