Low-Strength Steel Square-Neck Elevator Bolts
About half the strength of medium-strength bolts, these steel bolts are good for light duty applications. They 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. A square neck keeps these bolts from turning when tightening a nut. Zinc plating provides corrosion resistance in wet environments. Length is measured from the top of the head.

Medium-Strength Grade 5 Steel Square-Neck Elevator Bolts
Made from Grade 5 steel, these bolts are suitable for fastening most machinery and equipment. They have a smooth, low-profile head that provides a flush fit when installed. They're commonly used in tight spaces with moving parts, such as grain elevators and other belting systems, but can also be used in leveling and work-holding applications. A square neck keeps these bolts from turning when tightening a nut. They are zinc yellow-chromate plated to resist corrosion in wet environments. Grade 5 steel bolts are marked with three radial lines. Length is measured from the top of the head.

Stainless Steel Square-Neck Elevator Bolts
Made from stainless steel, these chemical-resistant bolts have a square neck that keeps them from turning when tightening a nut. They're 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.
18-8 stainless steel bolts have good chemical resistance and may be mildly magnetic.
316 stainless steel bolts are more corrosion resistant than 18-8 stainless steel bolts. They have excellent resistance to chemicals and salt water.

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.

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.

Weld Studs
Projections Below the Head
Projections Above the Head
These studs have a wide base that distributes the load and projections that concentrate the weld. Length listed is overall length.
Choose studs with below-head projection for a stronger hold that uses the full strength of the fastener. Pass these studs through a hole and weld them in place.
Choose studs with above-head projection to weld the screw directly to the surface of the material for a smoother appearance.
