About Hex Head Screws and Bolts
More
Fanged Elevator Bolts
Sharp teeth bite into the surface of wood, rubber belting, and other soft materials to keep the bolt from turning when tightening a nut. These bolts are commonly used in tight spaces with moving parts, such as grain elevators and other belting systems, because the smooth, low-profile head provides a flush fit when installed. Length is measured from the top of the head.
Zinc-plated steel bolts resist corrosion in wet environments.
