Fastener 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.

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.

Machine Keys

Rounded Machine Keys

When installed, these keys fill oval keyways completely, reducing stress on the key and shaft. The rounded ends make it easy to slide gears, hubs, and other components into place. These are also known as feather keys.

Machine Keys

Straight keys, with a square or rectangular cross section, are the most common type of key. Install them in keyways to transmit torque from shafts to gears and other components.

Woodruff Keys

Woodruff keys work well near shaft shoulders and on tapered shafts. These keys have a rounded shape that makes them easy to remove when parts need to be taken apart frequently. Use them in light duty applications to connect gears and other components to shafts. Also known as half moon keys.

Tapped Rounded Machine Keys

Thread a screw through the tapped hole to pop these keys out of a keyway. When installed, they fill oval keyways completely, reducing stress on the key and shaft. The rounded ends make it easy to slide gears, hubs, and other components into place.

Tapered Gib Keys

These keys have a tapered body that wedges in to the keyway for a more secure fit than standard machine keys. The gib head makes them easy to remove when parts need to be taken apart frequently, such as for maintenance or prototyping.

High-Profile Woodruff Keys

Feet prevent these keys from rocking in the keyseat. Woodruff keys work well near shaft shoulders and on tapered shafts. Use them in light duty applications to connect gears and other components to shafts. Also known as hi-pro keys.

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.

Step Machine Key Stock

When a keyway is damaged, cut a new, wider one. This key stock is stepped to match repaired keyways in shafts or gears. Cut it to length to create the machine key you need.

Rivets

Removable Locating Pins

A slightly undersized shank makes these pins easy to install and replace. Also known as slip-fit and lock-screw locating pins, they are held in place by a separate lock screw.

Cast-In Locating Pins for Plastics

Encase these pins while molding plastic or composite parts. Once set, the knurls resist movement, letting you align the workpiece with precision on a plate or table.

Through-Hole Alignment Pins

Precisely align drilled holes in two parts.

Slotted Bushings

When locating a workpiece using through-hole alignment pins, use one of these bushings and one standard bushing to prevent the pins from binding in your fixture.

Locating Pin Retractors

Use the handle on these retractors to extend and retract a locating pin, protecting the pin from damage in applications where fixtures move through a process, such as along a conveyor belt.

Air-Powered Locating Pin Retractors

A good choice for automated clamping, these retractors use compressed air to extend and retract a locating pin, protecting the pin from damage in applications where fixtures move through a process, such as along a conveyor belt.

Floating Locating Pins

The head on these pins slides side-to-side in one direction. Use one of these pins and one standard round-head pin to prevent jamming when loading and unloading workpieces with inconsistent hole spacing.

Press-Fit Locating and Support Buttons

Support and position workpieces and fixtures from the bottom or side. These buttons press into a drilled hole for permanent installation.

Screw-Mount Locating and Support Buttons

Mount through the counterbored hole with a socket head cap screw to support and position workpieces and fixtures from the bottom or side.

Sealed at the top to prevent debris from getting inside and making them seize up, these guide pins are a good choice for machining fixtures.

Installation Tools for Spring-Loaded Guide Pins

Use these tools for easier guide pin installation.

Threaded Spring-Loaded Guide Pins

Threading makes these guide pins easier to remove and replace than press fit, so they're useful for high-wear applications.

Create-Your-Own Spring-Loaded Guide Pins

Thread in a screw, handle, or other part to create the right size and shape guide pin for your application.

Spring-Loaded Guide Plungers

As the face of these plungers is pushed in, the internal spring applies outward pressure to hold a workpiece in position against stops and rails.

Spring-Loaded Guide Plungers for Thin Workpieces

Set the tang in a slot below the work surface to prevent thin material from sliding underneath the face.

High-Precision Index Plungers

To align two parts with more precision than standard spring plungers, these index plungers have a mating bushing that improves alignment and repeatability.

Spring-Loaded Work Supports

Slide these low-profile supports under a workpiece to provide support and reduce vibration.
