Product Overview

Elevator Bolt sourcing essentials

Elevator bolts have a very thin, wide flat head and a square neck under the head. Originally designed for grain elevator buckets, they are used wherever a low-profile wide head is needed — conveyors, screen plates, and bin liners. The flat head sits flush against the surface and the square neck prevents rotation.

Buyer Questions

Frequently asked questions

What makes elevator bolts low-profile?

The head is unusually thin compared to its diameter — typically 1/8" or less head height for a 3/8" diameter bolt. This minimum profile prevents grain or material from catching on the bolt head as it travels through the elevator or conveyor.
