Low-Strength Steel Coupling Nuts
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.

Steel Extra-Long Coupling Nuts
Also known as sleeve nuts, these are at least twice the length of standard coupling nuts to provide more room to connect and extend long lengths of threaded rods.

Left-Hand to Right-Hand Female Hex Thread Adapters
Often called sleeve nuts, these thread adapters fasten parts with right-hand threads to parts with left-hand threads.
Zinc-plated steel adapters are strong and corrosion resistant.

Acme Lead Screws and Nuts
Found in hand-powered clamps, vises, grates, doors, and work tables, lead screws and nuts have broad, square threads that are well suited for quick assembly, high clamping forces, and lifting and lowering heavy objects. To ensure compatibility, please select components that have the same thread direction and size.
Carbon steel components are easier to machine than alloy steel components.
Travel distance per turn, also known as screw lead, is the distance a nut or handle moves with one revolution of the lead screw.
For technical drawings and 3-D models, click on a part number.
Coupling nuts connect two lead screws.
