K= friction coatings, lubrication, and Assembly factors can alter these Values . Values in this chart are advisory only, all applications does not specify tightening torques. Generally the full effort of an ironworker with a ordinary spud wrench is sufficient to tighten the nuts on anchor the design engineer to determine the proper tightening Torque or if pretensioning is required for your State Bolt & Nut Co. - Confidential5/20/2016 All Thread Stud Cutting in:Phoenix, AZTucson, AZDenver, COAlbuquerque, NMTensile Strength (ksi)Carbide Solution Treated 316 S/SHeat Treated Medium Alloy SteelHeat Treated Alloy SteelLow Alloy Steel304 Stainless Steel316 Stainless SteelCarbide Solution Treated 304 S/SProduct available as Domestic or ImportLow Carbon SteelASTM A193 Grade B7304 Stainless Steel316 Stainless SteelASTM A193 Grade B8 ASTM A193 Grade B8M1/4 - 2 1/2"1/2 - 4"1/2 - 3"AllAllAllAll75 minimumN/A1/4 - 1"1 1/8 - 1 1/2"1 5/8 - 3"ASTM A449 ASTM A307A120 minimum105 minimum90 minimum1/4 - 4"60 minimumOthers by Special OrderASTM f1554 Grade 55 ASTM f1554 Grade 105125 - 150 58 - 8075 minimumASTM f1554 Grade 3630 minimumLow Carbon SteelHeat Treated Alloy Steel, 4140/414292 minimum81 minimum58 minimum105 minimum75 - 12075 - 12540 minimum40 minimum30 minimum125 minimum105 minimum36 minimumMaterialSpecificationColor codes for painting the ends of f1554 Graded rods.
