1. Rationale

To change the hardness deviation on hot dip galvanize washers from R/C 26-45 to R/C 36-45. The hardness should not be compromised by deviating 10 rockwell C points. With todays hot dip galvanize practices the hardness should be maintained with slight deviation. The current deviation allows the washer to crush or have impressions when used in applications with mating parts above R/C 26.
