Use these steel set screws for light duty holding.

These set screws have good chemical resistance.

Use the square head to turn these screws by hand, or use a wrench when you need more torque. Also known as half dog-point set screws, they have a protruding tip that locks within a mating hole or slot to keep parts aligned.

Turn these metric screws by hand using the hex head, or tighten them with a wrench for extra torque. With an extended tip that locks into a mating hole or slot—sometimes known as a dog point—they are often used to align and secure parts such as gears and pulley wheels.

The mounting plate provides a flat surface for supporting loads.

Attach these fittings to the end of a screw jack to create pivoting connections with clevis rod ends and other linkages.

Low-friction ball bearings allow these screw jacks to use half the power required by an Acme screw jack to lift the same load. Typically used as actuators, they run at higher speeds than Acme screw jacks.

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.

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.

Combine with an externally threaded acme nut to create a custom flange nut.

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.

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

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.

Keep your ball screw spinning without the ball nut damaging your system. When the ball nut reaches the stop pin at either end of the ball screw, it disengages and begins to idle.

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

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

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

A set of ball bearings reduces friction and secures the end of a metric ball or lead screw.

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.

The turning bar gives you leverage to lift heavier loads than wrench-adjustable screw jacks.

Mount these jacks to equipment to raise and level it.

These jacks have a short body to fit in low-clearance spaces. The handle pumps from side to side, requiring less vertical space than other bottle jacks.

The screw adjustment allows you to make small changes to the height of your load.
