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.

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

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.

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

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

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.

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.

Alloy steel set screws dig into hard surfaces for a secure hold.

More corrosion resistant than 18-8 stainless steel set screws, these have excellent resistance to chemicals and salt water.

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

A swivel caster lets you reposition your load.

These jacks have a short body to fit in low-clearance spaces.

The ratcheting action makes adjusting these jacks under load easier than screw jack stands.

After raising a load, add these steel stands for support.

Adjust the horizontal screw to hold workpieces of varying sizes in precise positions.
