Locators, Supports, and Stops

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.

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.

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.

Domed-Head Locating and Support Buttons

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

Swiveling Locating and Support Buttons

The swiveling tip supports uneven and angled surfaces.

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.

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.

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.

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.

Fixture Keys

Sized to fit with precision in machine table T-slots, use these keys to locate fixtures and vises on your machine table.

Hole-Mount Fixture Keys

Install these keys in a drilled and reamed hole to locate fixtures and vises on your machine table. Also known as sine keys.

Spring-Loaded Work Supports

Slide these low-profile supports under a workpiece to provide support and reduce vibration.

Ball-Lock Quick-Change Fixture Clamps

Build these components into fixture plates, machine subplates, and tombstones for quick changes. The system clamps and locates at the same time for accurate positioning with repeatability of ±0.0005".
