Use these steel set screws for light duty holding.

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

These metric screws have a square head, so you can turn them by hand or use a wrench for 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.

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.

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

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.

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.

Precision cut threads make these metric ball screws approximately four times more accurate than standard ball screws. Use them when exact positioning is essential.

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

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

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.

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 handle pumps from side to side, requiring less vertical space than other bottle jacks.
