Also known as universal clevis pins, these pins have holes on 1/4" centers so you can change the length by moving the cotter pin.

These pins have multiple through holes; change the length by moving the cotter pin. The bend makes them easy to insert and pull out.

Install or remove these pins from either side.

The wire retainer snaps closed to secure the pin for a one-piece alternative to a clevis and cotter pin combination. Also known as PTO pins.

Install or remove these pins from either side. Slide a retaining ring into the groove for a secure hold that takes up less space than a cotter pin.

These one-piece fasteners lock in place with a toggle. Flip the toggle to release the pin.

Spring force holds pieces of telescoping tubing together. Also known as snap buttons and tubing buttons.

These pins have a low-profile head, so they won't get knocked out of place. A spring-loaded, nonlocking retaining ball pops out when the pin is pushed through a hole, and retracts when the pin is pulled out.

A smooth ball handle is easy to grip and won't catch on other 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.

A T-handle makes these pins easy to grip. The shoulder keeps a portion of the pin outside the hole and makes them easy to grab.

Also known as hitch pin clips and R-clips, these pins are easy to install and remove.

Slide the pin through a hole then snap the ring down to lock these pins in place. Also known as click pins.

Also known as safety pins, these are easy to install and remove. Tension keeps them closed.

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.

Clip these pins onto grooved shafts and clevis pins with retaining ring grooves.

Twist these rings on to lock pins in place. They don't have the sharp ends of other cotter 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 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.

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.

Use these pins to fasten components made of soft materials such as plastic or aluminum. Opposing barbs bite into each piece, pulling them together for a tight, secure fit.

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

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.

A rounded bottom allows these keys to rock in their seat to relieve stress on the shaft caused by vibration or misalignment.

Make a key that is the exact length you need. Slightly larger than the size listed, these oversized keys offer a tight fit in worn keyways.

Add a stud to thin material when you only have access to one side.

These studs are also known as hanger bolts—use them to hang, mount, and fasten parts to wood structures.

A zinc plating provides corrosion resistance in wet environments.

Drive these tools with a hammer to expand anchors.

A zinc plating provides corrosion resistance in wet environments.

Turn the bolt to expand the nut for a secure hold in concrete. These anchors are often used to anchor machinery.

Also known as tank-strap bolts, these T-bolts are commonly used with a band clamp or a strap to hold fuel tanks and other objects in place.

Also known as flat-head Type 21 screws.

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.
