Reference

①,Thickness of the washer face shall be not less than 0.015 in. nor greater than 0.025 in, for screw sizes 3/4 in. and smaller, and not less than 0.015 in. nor greater than 0.035 in. for screw sizes larger than 3/4 in. The washer face is not applicable to hex flange or lobed head screws. The washer face diameter shall be equal to the maximum width across flats with a tolerance of -10%. Measurement of the washer face diameter shall be taken 0.004 in. below the bearing surface plane toward the head of the screw.
②,b is a reference dimension tntended for calculation purposes only. When screw length L ≤ 6 in，b=2d+0.25；when L＞6 in，b=2d+0.5 。
