Metric Black Stainless Steel Flat Washer DIN 125A
General Purpose, Standard Outer Diameter

Flat washers are placed under a bolt head or nut to evenly distribute the load of the fastener over a wider area. Washers also provide a smooth bearing surface against the work surface, protecting it and preventing damage.

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.

Stainless steel washers are commonly used in damp environments. They are popular across a wide range of industries: automotive, agriculture, architectural, sanitation, food processing, clean energy, etc.
