Elevator Bolt

Elevator bolts are fasteners with a broad, flat, thin head and a square neck directly under the head. The wide head provides a large bearing surface, which helps spread load over softer materials and reduces pull through. The square neck is designed to lock into a square hole or bite into wood so the bolt does not spin while the nut is tightened.

Elevator bolts are commonly used in conveyor and bucket elevator systems, as well as in wood and light duty industrial assemblies where a low profile head is needed. They are typically installed from the side where a smooth, flush head is desired, with the nut and washer on the opposite side. When selecting elevator bolts, match the thread size and length to the joint thickness and confirm the square neck dimensions suit the hole or material so the bolt can resist turning during tightening.
