The Washer will be according to ISO 7089 . 2. Material High grade carbon/alloy steel, Mild steel & stainless steel etc. 3. Hardness According to 100 HV, 200 HV, 300 HV or more as per requirement. 4. Coating & Marking will be done as per requirement. 5. All dimensions are in millimetres.

The only slight possible difference is that there is a manufacturing tolerance allowance of 1mm above or below the dimension stated in the form table. The thickness of the washer should not vary away from the thickness stated in the table because all washers are made from standard sheets of metal that are themselves standardised in thickness.

In fact, both attributes are applied to all of our products, including our other washers, shims, spacers, metal discs, and lock plates. The tight tolerances we can offer for our precision thrust washers are: Flatness: 0.001 inches (0.025 mm) Parallelism: 0.001 inches (0.025 mm) Thickness: +/- 0.0004 inches (0.010 mm)

Washer Thickness may very +/- .007 depending on production run; IFI Tolerances Apply; 304 stainless steel flat washers are corrosion resistant
