As the face of these plungers is pushed in, the internal spring applies outward pressure to hold a workpiece in position against stops and rails.

Sealed at the top to prevent debris from getting inside and making them seize up, these guide pins are a good choice for machining fixtures.

Thread in a screw, handle, or other part to create the right size and shape guide pin for your application.

Threading makes these guide pins easier to remove and replace than press fit, so they're useful for high-wear applications.

Lock the nose into the retracted position by pulling the handle and rotating it 90°.

Lock the nose into the retracted position by pulling the knob and rotating it 90°.

Retract the nose by pulling the knob.

Install by hand or with a hex key in low-clearance applications.

Lock the nose into the retracted position by pulling the ring and rotating it 90°.

A quarter turn of the handle locks these plungers in the retracted position. The T-handle is easy to grip.

Add a knob or handle to the threaded shank.

A smooth ball handle is easy to grip and won't catch on other parts.

Lock the nose into the retracted position by pulling and rotating the knob.

Install with a driver.

A flange keeps the plunger from being pushed through a hole when the ball is depressed.

These spring plungers have a nose that is about three-times longer than standard long hex-nose spring plungers.

Install with a hex key for more torque than slotted ball-nose spring plungers.

The flangeless design allows these spring plungers to mount flush with a surface.
