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.

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.

Add a flat mounting surface to a ball screw jack to support loads.

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.

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.

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

Also known as trapezoidal-thread lead screws and nuts.

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

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

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.

Internal ball bearings provide smooth low-friction travel in applications that require high speeds, accurate positioning, and repeatable movement. Also known as single-start metric ball screws and nuts, these have a single thread that runs the length of the screw.

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 ball or lead screw.

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.

Wrench-adjustable jacks require less clearance to turn than bar-adjustable jacks.

Fit these compact jacks under low-height loads.

A swivel caster lets you reposition your load.

Push or pry apart material with these rams by attaching them to a hydraulic pump.

Connect up to four rams and a gauge to a pump. Ram connections have flow-adjustment valves to adjust ram speed, or shut it off to temporarily hold a load.

Jacks include a ram, a hand pump with hydraulic oil, a pressure gauge, and a hydraulic hose.

Thread one of these plates onto your ram and use the four mounting holes to secure it in place.

Control the flow of oil to adjust ram speed, or shut it off to temporarily hold a load.

This steel-reinforced hose has male threads.

Use these versatile jacks for lifting, spreading, bending, pushing, and straightening.

With fewer moving parts than standard bottle jacks, these are made for frequent use.

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.

As versatile as bottle jacks, but with two lifting points—a toe for lifting loads low to the ground, and a saddle for a higher, more stable lifting point.

Roll from job to job and under hard-to-reach places.
