Seat Bolt

A seat bolt is a cold-formed fastener used to fix a seat to its frame or base. It holds the seat in place and can be removed for service or replacement.

A seat bolt fastens seats to frames in vehicles and public seating. It often takes a nut and washer of the same thread and class. A spanner or socket sets it.

Seat bolts are often made in carbon steel, and some are made in stainless steel for damp or outdoor seating. Match the material to the conditions the seat will see.

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, where the steel grade matters, a mill test certificate. On receipt, check the thread, head form and dimensions against the order, and look for cracks or poor forming.
