Elevator Bolts

Elevator bolts typically range from 1/4" to 5/8" in diameter, with lengths from around 3/4" up to 4" or longer depending on bucket style and belt thickness. The correct size depends on the bucket elevator's load capacity, belt or chain specifications, and the specific AA, CC, or continuous bucket style being installed.

Elevator bolts get their name from their original and most common use: securing buckets to the belts of grain and bucket elevators. Their distinct flat, round head design allows for a smooth, low-profile fit against conveyor belts, minimizing snagging and wear during continuous vertical material handling operations.

Elevator bolts are sometimes referred to as bucket elevator bolts or, due to their large flat head design, as sign bolts, since similar hardware is used in signage mounting. Regardless of the name, the design purpose remains consistent: providing a smooth, wear-resistant fastening surface.

Elevator bolts are commonly manufactured from high-strength carbon steel with zinc plating for corrosion resistance, suitable for most agricultural and industrial environments. For chemical, or highly corrosive applications, stainless steel options are also available to extend service life and maintain performance standards.

Selecting the correct elevator bolts depends on your bucket style (AA, CC, or continuous), belt or chain thickness, load capacity, and the materials being handled.
