Fastening and Joining

Taper Pins

To remove these pins, hit the small end with a punch to drive the pin out.

Threaded Taper Pins

Threads on these pins stick out for easy removal from blind holes. Tighten the hex nut to draw the pin out.

Tapped Taper Pins

These internally threaded pins sit flush in an assembly. For easy removal from a blind hole, thread a screw into the pin and pull out.

Hole-Alignment Pins

Line up holes by driving these pins through existing rivet, pin, and bolt holes in multiple pieces of metal. Alternatively known as lineup taper punches.

Double-Taper Hole-Alignment Pins

When one side wears out, use the other one. Also known as barrel drift pins.

Impact-Resistant Hole-Alignment Pins

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

No-Strike Hole-Alignment Pins for Flange Bolt Holes

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

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

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.

Locating Pins

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

Shoulder-Style Locating Pins

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

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.

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.

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.

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.
