WebBolt torque is calculated for a flanged assembly using the following equation. Applied Torque, T= (k∙f∙d)/12 in FPS Unit Where: T=Torque in ft-lb k=Dimensionless nut factor or tightening factor f=axial force in pounds d=Nominal bolt diameter in inches In the Metric System, Torque Applied, T = (k.d.f)/1000 where T = Torque in N-m f = Bolt load in N WebScrew Thread Stress Area Table Critical bolt thread stress area chart is given below for sizes 0-60 UNF to 1 1/2 - UNF. Capacities of ASTM A36 Steel Threaded Rods used for Pipe Support Hangers Based on allowable stress of 12,000 psi reduced by 25% using root area in accordance with ASME Standard B31.1 and MSS Standard SP-58.
TORQUE-TENSION REFERENCE GUIDE - Fastenal
WebThe following torque values are suggested maximums based upon actual lab testing on clean and dry or near dry fasteners. For other friction conditions, significant modifications may be required. Values though 7/16-inch diameter are stated in inch-pounds: ½-inch and over are stated in foot-pounds. Bolt Size. 18-8 Stainless Steel. Web1. Tightening torque values are calculated from the formula T = KDP, where T = tightening torque, lb-in.; K = torque-friction coefficient; D = nominal bolt diameter, in.; and P = bolt clamping load developed by tightening. lb. 2.
