Tap bolts are hex head bolts with a fully threaded shaft, sometimes referred to simply as full thread hex bolts. There are countless applications for tap bolts, but often, a secure connection will require a nut on the far side of the material. Many projects will prefer a bolt that is fully threaded, such as a tap bolt, to reduce the risk of bending or shearing under pressure. The threads distribute the load evenly along the full length of the bolt, therefore, reducing the risk of failure. Certain applications that require precise alignment and secure connections might call for use of tap bolts to ensure a reliable connection.
