T-Bolts

T-Bolts with Collar

Also known as clamping pins, these bolts have a collar that slides along the shaft and can be welded in place to clamp work in place and prevent over torquing.

T-Bolts

Also known as tank-strap bolts, these T-bolts are commonly used with a band clamp or a strap to hold fuel tanks and other objects in place.

Pins

Quick-Release Pins

A spring-loaded retaining ball pops out to hold these pins in place.

Clevis Pins

An alternative to bolts and rivets, these pins have a locking feature, such as a hole for a cotter pin, that is used to secure them.

Other Clamping Pins

Spring Plungers

A spring projects the nose to apply accurate, consistent pressure for positioning, indexing, and ejecting parts.

Locating Pins

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

Locating and Support Buttons

Made to tight tolerances, use these rests to support and position workpieces and fixtures from the bottom or side.

Spring-Loaded Guides

Use spring force to push workpieces into position against stops and rails. The internal spring allows easy insertion and removal of parts in a fixture and accommodates slight variations in size from part to part.

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.

Fixture Clamps

Build these clamps into a machining fixture to hold multiple workpieces.

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.
