The torque figures for a finely-threadedfastener as compared to a coarsely-threaded fastener of the same diameter may be slightly higher but not significant enough to note.Courtesy of Petersen Publishing CompanySAFETY NOTICETHERE ARE MANY VARYING FACTORS WHICH AFFECT TORQUE. THE FIGURES IN THISCHART ARE SAFE FIGURES FOR STANDARD TORQUE APPLICATIONS ONLY.C-5
