Selecting Compatible Lead Screws and Nuts

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.

Clamping Acme Lead Screw Collars

Thread these one-piece collars onto an Acme lead screw.

Two-Piece Clamping Acme Lead Screw Collars

Mount these two-piece collars anywhere on an Acme lead screw without removing components.

Precision Acme Lead Screws and Nuts

Also known as single-start and self-locking lead screws and nuts, these have a single thread that runs the length of the screw. The nut travels only when the screw turns, so your system won't unexpectedly move when the lead screw is at rest.

Fast-Travel Precision Acme Lead Screws and Nuts

Multiple thread channels (also known as thread starts) create faster linear travel than lead screws with a single thread start.
