Pins

Dowel Pins

Use these metal dowel pins as pivots, hinges, shafts, jigs, and fixtures to locate or hold parts.

Dowel Pin Stock

Cut this 12" stock to the length you need.

Full-Groove Dowel Pins

Grooves run the full length of these pins for a firm hold that won't spin. Use them in place of standard dowel, spring, and taper pins to fasten parts. Also known as type A pins.

Half-Groove Dowel Pins

These pins make good hinges or pivots. The grooved half locks pins in position, while the smooth half can act as a pivot. Also known as type H pins.

Center-Groove Dowel Pins

Center-groove pins are often used in place of clevis pins or to create T-handles. The grooved center locks pins in position, while the smooth ends act as a pivot. Also known as type E pins.

Half-Groove Dowel Pins with Notch

These pins are commonly used as anchors for tension springs. The grooved half locks pins in position, and spring ends fit in to the notch. Also known as type G pins.

Quarter-Groove Dowel Pins

Quarter-groove pins are well suited for hinges or pivots. The grooved end locks pins in position, while the smooth portion can act as a pivot. Also known as type C pins.

Ring-Grip Quick-Release Pins

The smooth ring handle on these pins won't catch on parts. A spring-loaded, nonlocking retaining ball pops out when the pin is pushed through a hole, and retracts when the pin is pulled out.

Core Pins

These pins have a flat head to fit into a counterbored hole.

Flush-Mount Core Pins

A 60° beveled head fits into a countersunk hole.

Ejector Pins

Push parts out of molds with these hardened pins. Also known as knockout and forged pins.

Punch Pins

Use these pins with a die to punch 1/8" and larger holes. Pins can be modified to fit your application.

Cotter Pins

Also known as split pins, these have one prong slightly longer than the other so they’re easy to open. Bend prongs outward to secure.

Hammer-Set Cotter Pins

For parts that spin or are otherwise difficult to access, slide these pins in and tap them with a hammer for a temporary hold. Reposition work, then bend the prongs outward to secure.

Slotted Spring Pins

Also known as roll, tension, split, and expansion pins, these pins have a slot along one side that you squeeze closed to install them into unthreaded holes.

Coiled Spring Pins

These spiral pins remain flexible after installation, so they absorb shock and vibration better than slotted spring pins. They work well in holes that are out of round.

Through-Hole Weld-On Pins

Pass these pins through a mounting hole and weld the head to the surface.
