About Washers

Metric Oversized Washers

Compared to our general purpose washers, these have exaggerated diameters and/or thicknesses. Use them to cover oversized holes, hold heavy fastening loads, or as spacers and levelers.
Stainless steel washers are more corrosion resistant than steel washers, and almost as strong. Use them in damp and washdown applications without worrying about rust. Bumax 88 stainless steel washers are the most corrosion resistant washers in our offering. They're commonly used in marine environments and chemical-processing plants.
Washers that meet DIN and ISO specifications meet international standards for washer dimensions. ISO 8738 is formerly DIN 1440. ISO 7093 is formerly DIN 9021.
