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.

Setup Studs
Combine these setup studs with T-slot nuts, flanged nuts, setup clamps, or setup blocks to clamp and hold workpieces, vises, and other objects onto your fixturing table. Also known as double-ended studs, they have threads on both ends. One end threads into a T-slot nut or flanged nut inside the table. The other end passes through a setup clamp and secures with a nut and washer. The middle of the stud is unthreaded for gripping and adjusting the stud.
These setup studs are also used to align parts during assembly. One end of the stud is threaded into the part being added, and the other end fits into the mounting hole of the mating part. Because the studs don't have a head, you have the option to thread them into holes from either end, but they require a nut. You can adjust the distance between the mating parts by tightening and loosening the nut.
Black-oxide steel studs have a protective coating that resists corrosion in dry environments.

Vibration-Resistant Setup Studs
Also known as tap-end and fixture studs, these rods have friction-fit threads on one end to resist loosening and standard threads on the other end for attaching a nut. They are ideal for machining applications where vibration can loosen clamps. Remove studs with pliers to reuse them.
Inch studs have a Class 5 thread fit on the friction-fit end and Class 2A thread fit on the machine-threaded end.
Stainless steel studs have excellent corrosion resistance.
