Locators, Supports, and Stops

Spring-Loaded Guide Pins

As the workpiece pushes against the pin head in one direction, the internal spring pushes back to hold it in place for clamping.

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.

Installation Tools for Spring-Loaded Guide Pins

Use these tools for easier guide pin installation.

Threaded Spring-Loaded Guide Pins

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

Create-Your-Own Spring-Loaded Guide Pins

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

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.

Spring-Loaded Guide Plungers for Thin Workpieces

Set the tang in a slot below the work surface to prevent thin material from sliding underneath the face.

High-Precision Index Plungers

To align two parts with more precision than standard spring plungers, these index plungers have a mating bushing that improves alignment and repeatability.
