About Hex Head Screws and Bolts
More
Ribbed Elevator Bolts
Ribs under the head dig into the surface of soft metal and plastic 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.
Black-oxide steel bolts are mildly corrosion resistant in dry environments.
Zinc-plated steel bolts resist corrosion in wet environments.
18-8 stainless steel bolts have good chemical resistance and may be mildly magnetic.
