Washers are short spacers, usually round in shape, either drilled through or with a threaded hole. Some washers are manufactured with features that inhibit spinning/loosening, such as split washers, or toothed washers, and others are made of bent or beveled material that act as springs. Washers can be used to provide spacing between components, allow a wider contact area when fastening with screws, provide thermal or electrical isolation, inhibit loosening, or provide a small degree of spring pressure.
ASM washers are available in a variety of materials, both metallic and non-metallic, with sizes ranging from .040 to 3.5″ OD and .020 to 3″ ID.
ASM’s refined manufacturing processes can hold tighter tolerances than the industry standard and allow for the fastest turnaround of parts as needed. Part lengths can be modified to suit any customer requirement. ASM’s quality management system is AS9100D and ISO9001:2015 certified. DFARS documentation is available upon request.
