Acme 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.

Metric Lead Screws and Nuts

Metric Lead Screws and Nuts

These metric lead screws and nuts have broad, square threads that are well suited for quick assembly, high clamping forces, and lifting and lowering heavy objects. They're commonly found in hand-powered clamps, vises, grates, doors, and work tables.

Precision Acme Lead Screws and Nuts

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

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.

Metric Precision Lead Screws and Nuts

Metric Precision Lead Screws and Nuts

Also known as trapezoidal-thread lead screws and nuts.

Ultra-Precision Lead Screws and Nuts

Ultra-Precision 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 Ultra-Precision Lead Screws and Nuts

Fast-Travel Ultra-Precision Lead Screws and Nuts

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

Clamping Acme Lead Screw Collars

Clamping Acme Lead Screw Collars

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

Two-Piece Clamping Acme Lead Screw Collars

Two-Piece Clamping Acme Lead Screw Collars

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

Metric Clamping Lead Screw Collars

Metric Clamping Lead Screw Collars

Install these threaded collars on a metric lead screw to separate and position components, or use them as an end stop to limit travel.

Self-Reversing Lead Screws and Nuts

Self-Reversing Lead Screws and Nuts

A crisscross thread pattern allows you to drive the nut back and forth without changing the lead screw's direction of rotation. When the nut reaches one end of the lead screw, it changes direction and travels back to the other end.

Threadless Lead Screw Nuts

Threadless Lead Screw Nuts

Install these nuts on a rotary shaft to create a linear positioning system without a lead screw. Instead of threads, a set of angled ball bearings drives the nut along a shaft as it spins.
