Mounting Bases for Spring Plungers

Mount ball-nose and long-nose spring plungers to fixture surfaces.

Drivers for Spring Plungers

Install spring plungers from the nose end without depressing the nose.

Locating Pins

Through-Hole Alignment Pins

Precisely align drilled holes in two parts.

Slotted Bushings

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.

Threaded Locating Pins

Screw the shank into a threaded hole for quick installation and removal.

Shoulder-Style Locating Pins

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

Locating Pins

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

Mating Locating Pins and Hole Liners

Maintain consistent alignment in mating parts by installing a pin in one part and a liner in the other.

Cast-In Locating Pins for Plastics

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.

Removable Locating Pins

A slightly undersized shank makes these pins easy to install and replace. Also known as slip-fit and lock-screw locating pins, they are held in place by a separate lock screw.

Floating Locating Pins

The head on these pins slides side-to-side in one direction. Use one of these pins and one standard round-head pin to prevent jamming when loading and unloading workpieces with inconsistent hole spacing.

Spring-Loaded Guides

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.

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.

Locating and Support Buttons

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.

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.

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.

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".

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.
