A wide tip provides more gripping power than standard swivel-tip set screws. To use, remove the tip, thread the screw through the hole, and attach the tip on the other side.

Use these tube-end weld nuts with left-hand threaded fasteners.

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.

Also known as trapezoidal-thread 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.

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

Also known as single-start ball screws and nuts, these have a single thread that runs the length of the screw. They operate with more torque than fast-travel ball 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.

Designed for use with right-hand, internally threaded rod ends, these rods have right-hand threads on both ends. Use them for remote valve operators, throttle controllers, shifting mechanisms, and virtually any push/pull assembly.

Similar to turnbuckles, these rods have right-hand threads on one end and left-hand threads on the other so you can make a linkage that adjusts for tension. Add right- and left-hand threaded rod ends to build your linkages.
