Headless Alloy Steel Precision Shoulder Screws

Without a head to get in the way, these screws fit in tight spaces where standard shoulder screws cannot. Either thread them in a countersunk hole for a flush mount, or install them with the shoulder sticking out to use them as pins or dowels for aligning and locating components.

Ring-Grip Clevis Pins

Easier to install and remove than standard clevis pins, these pins have a ring-grip handle.

Loop-Grip Clevis Pins

A large loop handle makes these pins easy to grip.

T-Handle Clevis Pins

A plastic-coated T-handle welded to these pins makes them easy to grab.

Toggle-Lock Clevis Pins with Handle

A swivel handle makes these pins easy to install and remove, while the toggle locks them in place. Flip the toggle to release the pin.

Ring-Grip Shoulder-Style Quick-Release Pins

The smooth ring handle on these pins won't catch on parts. The shoulder keeps a portion of the pin outside the hole and makes them easy to grab.

Keyed Double-Locking Quick-Release Pins

Use the key to unlock these pins, then press the button to release the spring-loaded retaining balls. Two-step locking prevents accidental removal.

Shoulder-Style Ejector Pins

A thick shoulder makes these pins more rigid than standard ejector pins.

No-Strike Hole-Alignment Pins for Flange Bolt Holes

Turn the pin and the tapered shaft forces the two holes into alignment.

Impact-Resistant Hole-Alignment Pins

Often called bull pins, these pins are designed to resist mushrooming caused by repeated pounding.

No-Strike Hex Head Alignment Pin Sets

The tapered shaft of these pins eliminates the need for hammering and prying when aligning flange bolt holes.

Locators, Supports, and Stops

Shoulder-Style Locating Pins

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

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.

Threaded Locating Pins

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

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.

Through-Hole Alignment Pins

Precisely align drilled holes in two parts.

Tooling Balls

The shoulder on these tooling balls provides a consistent height reference point.
