Splice Bolt

A splice bolt is a fastener used to join two members end to end, often with a recess nut. It pulls the parts together and holds the joint.

A splice bolt joins two members end to end, often in a structural or rail joint. It passes through aligned holes in the splice plates and the members. A recess nut sits in a recess or counterbore and draws the joint tight.

Splice bolts are often made in carbon steel, and some are made in stainless steel for exposed joints. Match the material to the load and the weather the joint will face.

This is a general guide to checking this kind of part. It says nothing about any supplier's parts.

Ask for a certificate of conformance and a mill test certificate where the steel grade matters. On receipt, check the thread, length and nut fit, and look for damage to the recess.
