Chrome-Plated Steel Spacers

These chrome-plated steel spacers suit automotive wheel and tire assemblies that require a 5/16 in screw size and a 3/8 in overall length. The pack contains five pieces for small-scale jobs or maintenance stock.

Simple Bolt-Through Fitting

Each spacer slides over the stud or bolt and seats against the hub or wheel face without special tools. The retaining rib is not applicable, so alignment relies on the 0.344 in inside diameter matching the fastener; a loose fit can allow rotation under vibration.

For Light-Duty Inch-Series Builds

Builders working with 12L14 steel hardware in inch measurements will find the +/- 0.010 in tolerances on inside diameter, outside diameter and length consistent. Shops needing metric threads, thicker spacers or higher pack quantities should look elsewhere.

Questions about this item

How do I verify the spacer fits correctly after installation?

Measure the installed spacer with a caliper; the outside diameter should read 5/8 in within the +/- .010 in tolerance, the inside diameter 0.344 in within +/- .010 in, and the overall length 3/8 in within +/- .010 in.

What comes in the package and do I need to buy screws separately?

The pack contains five chrome-plated 12L14 steel spacers sized for 5/16 in screws; screws are not included and must be purchased separately.

Which version should I choose for a 5/16 in screw with a 3/8 in gap?

This MPB509 spacer is made for a 5/16 in screw size and provides a 3/8 in overall length, matching that exact requirement.
