Tighten these threaded rods by turning them to the left; once fastened, they resist loosening from counterclockwise motion. About half the strength of medium-strength steel threaded rods, use them for light duty hanging, mounting, and fastening.

Zinc-plated steel threaded rods are corrosion resistant in wet environments.

Also known as extension nuts, use these to connect and extend threaded rods. They're about half the strength of medium-strength steel coupling nuts for use in light duty fastening applications.

Zinc-plated steel coupling nuts resist corrosion in wet environments.

Hot-dipped galvanized steel coupling nuts have a thick coating for better corrosion resistance than zinc-plated steel nuts. They must be used with other hot-dipped galvanized fasteners.

Black-oxide steel coupling nuts have a dark surface color and are mildly corrosion resistant in dry environments.

Secure setup clamps and fixtures to your machine table, or assemble heavy machines, such as engine mounts. These studs act as a pilot when connecting parts since they’re headless, which eases installation. Unlike a bolt, which has a head, they let you access parts from either end, but they require nuts to hold the part. Pair them with a T-slot or flanged nut when securing to a machine table. Or, put a nut on before your part to work as a float, allowing you to adjust the height of your part. The unthreaded middle is useful for gripping and adjusting. Also known as double-ended studs.

Steel studs are stronger than stainless steel studs. Black-oxide steel studs resist rusting in dry environments.

DIN studs meet dimensional and material requirements.
