Metric Black Stainless Steel Extra Thick Fender Washer
Use on oversized holes to distribute the load of the fastener over a wider area.
Almost 3X as THICK as regular flat washers, extra thick washers are sometimes used as spacers. Washers also provide a smooth bearing surface against the work surface, protecting it and preventing damage.
Material: Stainless Steel
Suitable for damp locations
Corrosion resistant
Finish: Black Oxide
- Abrasion resistant, does not peel, chip or rub off
- Reduces friction, prevents galling
- Does not change the strength of the stainless steel
- Practically no dimensional change to base fastener
- The spray applied during the coating process wears off over time, revealing an attractive matte black finish
The black oxide coating per MIL-DTL-13924, Class 4 on 300 series corrosion resistant steel meets 96 hours of resistance in a 5% salt spray (fog) test in accordance with ASTM B117. We recommend using stainless steel installation tools to prevent extraneous rust.
Also known as thick washers for heavy spring-type pins
