Locators, Supports, and Stops

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.

Threaded Locating and Support Buttons

Use these buttons to support and position workpieces and fixtures from the bottom or side. Their hex shape lets you screw them into a threaded hole with a wrench or socket.

Press-Fit Locating and Support Buttons

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

Swiveling Locating and Support Buttons

The swiveling tip supports uneven and angled surfaces.

Domed-Head Locating and Support Buttons

Support rounded or irregularly shaped workpieces from the bottom or side with minimal contact.

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.

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 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.

Locating Rails

For locating the side of a workpiece without milling a permanent slot into your fixture, screw these easily repositioned rails into threaded holes.

Locating and Support Pads

With a larger contact surface than locating and support buttons, these pads can support large workpieces and fixtures. They're also known as rest pads.

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.

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.
