Steel Feet | McMaster-Carr

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.

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.

Threaded Locating and Support Buttons

Use these buttons to support and position workpieces and fixtures from the bottom or side. Their hex shape lets you screw them into a threaded hole with a wrench or socket.

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.

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.

Domed-Head Locating and Support Buttons

Support rounded or irregularly shaped workpieces from the bottom or side with minimal contact.

Swiveling Locating and Support Buttons

The swiveling tip supports uneven and angled surfaces.

Swivel-Tip Gripper Screws

Screw these grippers into place and make quick height adjustments.

Grippers

Maintain a secure hold on uneven or irregularly shaped parts by clamping against these serrated grippers.

Side Grippers

Clamp against these grippers for a secure hold on workpiece edges.

Angled Grippers

The face of these grippers is angled 15°. They can be used in the jaws of lathe chucks.

Installation Tools for Spring-Loaded Guide Pins

Use these tools for easier guide pin installation.

Tooling Balls

The shoulder on these tooling balls provides a consistent height reference point.

Adjustable-Height Tooling Balls

Install tooling balls in a workpiece or fixture to create a precise measurement reference point. Push the shank further into the hole to adjust the height of the ball.

Tooling Ball Mounting Pads

Use a mounting pad when your tooling ball needs a raised mounting point.

Locating and Support Pads

With a larger contact surface than locating and support buttons, these pads can support large workpieces and fixtures. They're also known as rest pads.

Locating Rails

For locating the side of a workpiece without milling a permanent slot into your fixture, screw these easily repositioned rails into threaded holes.

Fixture Keys

Sized to fit with precision in machine table T-slots, use these keys to locate fixtures and vises on your machine table.

Hole-Mount Fixture Keys

Install these keys in a drilled and reamed hole to locate fixtures and vises on your machine table. Also known as sine keys.

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.

Clamps

Swiveling Tips for Screws and Threaded Studs

Attach to the end of a screw or threaded stud to apply uniform pressure on uneven and angled surfaces. Also known as toggle and swivel-foot pads.

Nonmarring Swiveling Tips for
Screws and Threaded Studs

The contact area is covered in plastic to protect soft metal and polished surfaces. Attach these tips to the end of a screw or threaded stud to apply uniform pressure on uneven and angled surfaces. Also known as toggle and swivel-foot pads.

Swiveling Gripper Tips for Screws and Threaded Studs

Attach to the end of a screw or threaded stud—the serrated face swivels to grip uneven and angled surfaces. Also known as toggle and swivel-foot pads.

Inside Diameter Fixture Clamps
for Castings and Rough Parts

These clamps wedge against the workpiece ID to grip cast, unfinished, or uneven parts, leaving the outside clear for machining.

Inside Diameter Fixture Clamps

Secure a workpiece from the inside, leaving the outside clear for machining.

Ball-Lock Quick-Change Fixture Clamps

Build these components into fixture plates, machine subplates, and tombstones for quick changes. The system clamps and locates at the same time for accurate positioning with repeatability of ±0.0005".

Drill Bushings

Press-Fit Drill Bushings with Head

The head prevents these bushings from being pushed through the jig when drilling pressure is extreme. The head sits above the jig plate or can be mounted flush by installing in a counterbored hole.

Metric Press-Fit Drill Bushings with Head

Even under extreme drilling pressure, these metric bushings won't press through your jig plate. A flanged head on the top of the bushing acts as a stop, preventing it from moving as you push down your drill bit, reamer, or other cutting bit.

Made-to-Order Press-Fit Drill Bushings with Head

Choose the ID, OD, and length you need.

Press-Fit Drill Bushings

Finish-Your-Own Press-Fit Drill Bushings

Larger OD tolerances than standard press-fit bushings allow for finishing. Bushings should be machine ground.

Metric Press-Fit Drill Bushings

Also known as jig bushings, these metric drill bushings fit inside fixture plate holes to guide drill bits, counterbores, reamers, and other cutting tools. They improve accuracy so that your drilled holes and cuts are consistent from part to part.

Removable Drill Bushings

Replace worn bushings and quickly change IDs without needing to repeatedly use a lever press. Instead of pressing bushings in and out of your jig fixture, which can cause damage, these bushings slide in and out of sleeves.

Removable Drill Bushings for Thin Metal

Insert these bushings into a drilled hole and twist the lock ring to secure. Reusable and easy to replace, they are held in in place by a separate locking part.

Secure-Hold Drill Bushings for Plastic

The knurls resist force and provide better holding strength than serrations. Encase in plastic tooling.

Drill Bushings for Soft Metal and Wood

The serrations at the top of the bushing grip to prevent rotation and spin out.

Drill Bushings for Plastic

The serrations grip to prevent rotation and spin out. Press or encase into plastic tooling.

Material Handling

Floor Locks

Floor locks bolt or weld to the underside of your equipment and have a spring-loaded base with a nonskid floor pad to keep equipment stationary.

Side-Mount Floor Locks

These locks bolt or weld to the side of equipment that can't accommodate a floor lock underneath. Compatible with a wide range of caster mount heights.

Shoes for Straight and Extension Ladders

Replace worn out shoes on straight and extension ladders.

Shoes for Step Ladders

Replace worn out shoes on step ladders.

High-Capacity Roller Conveyors

Rollers have a standard 1.9" diameter to fit most roller conveyors.

High-Capacity Large-Diameter Roller Conveyors

These rollers have 2 1/2" diameters.

Roller Conveyors

Easily move light- to medium-weight objects with flat or uneven bottoms.

Skate Wheel Conveyors

Skate wheel conveyors are for light duty loading and unloading of flat-bottom objects.
