Chrome-plated steel spacer for 5/16 in screws
This round spacer is made from 12L14 steel with a chrome-plated finish. It fits a 5/16 in screw size and has an inside diameter of .344 in. The outside diameter measures 5/8 in and the overall length is 1/2 in. It comes in a small pack of five pieces.
Tolerances and fit limits for the spacer
Inside diameter, outside diameter and overall length each carry a tolerance of +/- .010 in. There is no retaining rib and no hex width on this spacer. The inch-based measurements apply directly without metric conversion. These tolerances define the practical fit range for alignment and spacing tasks.
Replaces plain washers
The chrome plating adds corrosion resistance compared with bare steel spacers or simple washers. It is not suited for applications needing a retaining rib, a hex drive or a different length. The jump is worth it when a precise .010 in tolerance stack and a plated finish are required together.
