Pin Assortments

Slotted Spring Pin Assortments

Slotted spring pins are also known as roll, tension, split, and expansion pins. Because the slot is pressed closed when the pins are inserted, they don't flex after installation.

Coiled Spring Pin Assortments

Coiled spring pins are flexible after installation, so they absorb shock and vibration better than slotted spring pins. They also have higher dynamic load capacities and accommodate wider hole tolerances.

Dowel Pin Assortments

Dowel pins are commonly used as pivots, hinges, shafts, jigs, and fixtures to locate or hold parts. They're slightly oversized for a tight fit.

Clevis Pin Assortments

Clevis pins have a hole for a cotter pin on one end to lock them in place.

Cotter Pin Assortments

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

Hairpin Cotter Pin Assortments

Also known as hitch pin clips and R-clips, use these cotter pins in applications requiring quick installation and removal.

Hairpin Clip Assortments

Clip these pins onto grooved shafts and clevis pins to keep components in place.

Plug Gauge Sets

Take precision go/no-go measurements of hole sizes and depths, check hole location and distance, and set micrometers.

Target-Size Plug Gauge Sets

Get your choice of one target-size gauge with 12 larger gauges and 12 smaller gauges, graduated in 0.0001”. Also known as tenth-step gauges, they’re often used in metrology labs, quality control departments, and tool rooms for setting snap gauges and comparators.

Wear-Recognition Plug Gauge Sets

To indicate when you need to calibrate or replace the gauges in these sets, gauges have a black-oxide treatment that shows wear patterns.

Fastening Tools

Nonmarring Pin-Removal Punch Sets

Minimize damage to your work surfaces with these brass punches, which are softer than steel punches.

Impact-Resistant Pin-Removal Punch Sets

Impact-resistant steel makes these punches stronger and more durable than standard pin-removal punches.

Pin-Removal Punch Sets
