Oval OD Washer Frequently Asked Questions

Below are answers to some of the most common questions about oval OD washers.

What are oval OD washers?
Oval OD washers feature an elliptical outer profile with a round inner bore. The oval outer shape allows the washer to fit into oval slots, oblong openings, and non-standard mounting features where a round washer cannot be properly retained. Superior Washer stocks 7 oval OD configurations with IDs from 0.191" to 0.875" and ODs (major axis) from 0.500" to 1.900", defined by the OD major dimension and a B dimension representing the minor axis of the oval.

How are oval OD washers dimensioned?
Oval OD washers are described by the ID (round bore), the major OD axis (the longer dimension of the oval outer profile), the B dimension (the minor axis of the oval outer profile), and the thickness. The major and B dimensions together fully define the oval outer shape. Stocked thicknesses range from 0.040" to 0.125".

What applications use oval OD washers?
Oval OD washers are used in oval or oblong mounting slots where the washer must span the slot width and provide a bearing surface, or where the outer profile must conform to a non-round housing opening. Common applications include sheet metal assemblies, panel mounting, lighting fixtures, and custom mechanical enclosures.
