Also known as clamping pins, these bolts have a collar that slides along the shaft and can be welded in place to clamp work in place and prevent over torquing.

Flip the handle 180° to expand and contract the shaft for a tight, vibration-resistant fit.

Two holes in the plate allow these plungers to be mounted to a flat surface.

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

Quickly align, join, or hold machine components in place in food, pharmaceutical, and other sanitary environments. Pulling the plunger knob and twisting it 90° will lock the nose into its retracted position.

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

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

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

A quarter turn of the handle locks these plungers in the retracted position. The smooth ball handle is easy to grip and won't catch on other parts.

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

An L-handle takes up less space than a T-handle.

Install these spring plungers with a screwdriver—they're slotted on one or both ends.

Weld these catches in place for a strong permanent hold.

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

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

Install with a driver.

Noses are up to four times longer than standard long-nose press-fit spring plungers.

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

When locating a workpiece using through-hole alignment pins, use one of these bushings and one standard bushing to prevent the pins from binding in your fixture.

Install these pins in a plate or table and mate with holes in a workpiece for precise alignment.

The shoulder provides a consistent height reference point and keeps the pin from being pressed through the fixture.

Encase these pins while molding plastic or composite parts. Once set, the knurls resist movement, letting you align the workpiece with precision on a plate or table.

Use the handle on these retractors to extend and retract a locating pin, protecting the pin from damage in applications where fixtures move through a process, such as along a conveyor belt.

Support and position workpieces and fixtures from the bottom or side. These buttons press into a drilled hole for permanent installation.

Mount through the counterbored hole with a socket head cap screw to support and position workpieces and fixtures from the bottom or side.

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.

Use these tools for easier guide pin installation.
