Pins

Dowel Pins

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

Plastic Dowel Pins

Plastic pins are a nonconductive and nonmagnetic alternative to metal dowel pins. Use them as pivots, hinges, shafts, jigs, and fixtures to locate or hold parts.

Undersized Dowel Pins

Slip these pins in and out during maintenance or prototyping—they’re undersized to make alignment easier.

Oversized Dowel Pins

Oversized to fit worn and enlarged holes, these pins work well as repair and replacement parts.

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.

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.

Shoulder-Style Ejector Pins

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

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.

Heavy Duty Coiled Spring Pins

For tough jobs, these spiral pins are 30% stronger than our standard coiled spring pins. They remain flexible after installation to absorb shock and vibration, and work well in holes that are out of round.
