WebHardnesses are Brinell Hardness Numbers. The nut manufacturer, at his option, may add other markings to indicate the use of atmospheric corrosion resistant steel. Specifications —. ASTM A563 — Carbon and Alloy Steel Nuts. ASTM A194/A194M — Carbon and Alloy Steel Nuts for Bolts for High Pressure and High Temperature Service. WebTorque has been converted into ft/lbs by dividing the result of the formula by 12. All calculations are for Coarse Thread Series (UNC). Grade 2 calculations only cover fasteners 1/4" - 3/4" in diameter up to 6" long. For longer fasteners, the torque is reduced significantly. Clamp loads are based on 75% of the minimum proof loads for each grade ...
