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.

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.

Coupling nuts connect two lead screws.
