Twist-to-Lock L-Handle Retractable Spring Plungers

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

Twist-to-Lock Knob-Style Retractable Spring Plungers

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

Knob-Style Retractable Spring Plungers

Retract the nose by pulling the knob.

Designed with a flange to keep the plunger from being pushed through a hole when the ball is depressed.

Clamping and Workholding

Sealed Spring-Loaded Guide Pins

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.

Spring-Loaded Guide Plungers

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.

Screw-Mount Locating and Support Buttons

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

Inspection and Measuring Fixturing

Use these components in coordinate measuring machine (CMM) applications to raise a workpiece and reliably position it on a fixture plate with ¼"-20 holes.
