The tables in this document are for the convenience of the user only and are based on calculations which assume certain friction coefficients for the friction between studs and nuts, and between the nuts and the flanges face. Threads dimensions, surface finish of studs, nuts, flange face, degree of parallelism, lubrification, coating are some factors which affect the relationship between nut torque and stud stress. Two Coefficient of friction are used in the tables. A Coefficient of friction of 0,13 approximates the friction with threads and nut bearing surfaces being bare metal well-lubricated with thread coumpound tested in accordance with ISO 13678. A coefficient of friction of 0,07 approximates threads and nut face coated with fluoropolymer material Minimum B7 Stud Yield Strength in PSI: From Bolt size 3/4" up to 2 1/2": 105,000 psi - From Bolt size 2 3/4" up to 4": 95,000 psi - From 4" up to 6": 75,000 psi Tools recommandation are based on the concept "Best to Tight". User must anticipate the dissassembly. If no overhead limited clearance, RT Series w/ Square Drive using Impact Socket is perfect. Check on www.rapidtorc.com or email to sales@rapidtorc.com
