Dowel Pins

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

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.

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.

Split Rings

Also known as key rings, twist these rings into place to secure clevis pins, connect components, or add a pull handle. They don't have the sharp ends of other cotter pins.

Knob-Style Retractable Spring Plungers

Retract the nose by pulling the knob.

Twist-to-Lock Knob-Style Retractable Spring Plungers

Lock the nose into the retracted position by pulling the knob and rotating it 90°.

Pull-Ring Retractable Spring Plungers

The ring allows you to attach these spring plungers to a lanyard.

Twist-to-Lock Pull-Ring Retractable Spring Plungers

Lock the nose into the retracted position by pulling the ring and rotating it 90°.

Twist-to-Lock L-Handle Retractable Spring Plungers

Lock the nose into the retracted position by pulling the handle and rotating it 90°.

L-Handle Retractable Spring Plungers

Press-Fit Ball-Nose Spring Plungers

Designed with a flange to keep the plunger from being pushed through a hole when the ball is depressed.

Slotted Ball-Nose Spring Plungers

Install these spring plungers with a screwdriver—they're slotted on one or both ends.

Long-Nose Spring Plungers

Install with a driver.

Slotted Long-Nose Spring Plungers

Slotted on both ends for installation with a screwdriver.

Machine Key Stock

Cut this stock to length to create the machine key you need. Straight keys, with a square or rectangular cross section, are the most common type of key. Install in a keyway to transmit torque from shafts to gears and other components.

Decorative Finishing Nails

Also known as escutcheon pins, these nails have a domed head that sits above the surface.

Hole-Alignment Pins

Nonmarring Hole-Alignment Pins

These brass tools reduce marring on metal surfaces because they're softer than steel punches.

Nonmarring Hole-Alignment Pin Sets

These brass tools reduce marring on metal surfaces because they're softer than steel punches.

Hinge-Pin Mount Door Closers

There's no need to mount a closer to your door or frame—these take the place of an existing hinge pin.
