Use Prevailing Torque All-Metal Nut chart if using this style of nut. = Nominal Diameter. = Clamp Load For J429 Grade 5 and 8, FNL Grade 9, A574, Class 4.6, 8.8, 10.9 and 12.9, the clamp loads are listed at 75% of the proof loads specified by the standard. For A307 Grade A, 75% of 36,000 PSI is utilized.
TIGHTENING TORQUE GUIDE based on IFI 5th Edition Technical Data N-12/N-16, using Equation (1) and a torque coefficient, K-0.20 for non-plated steel fasteners and K-0.15 for plated fasteners. These figures represent an estimate of torque (torque being the measurement of friction, not tension) required to induce a given preload (clamp load) in a ...

Tightening Torque Guide for Grade 5 & 8 Hex Cap Screws. This table is based on IFI 5th Edition Technical Data N-12/N-16, using Equation (1) and a torque coefficient, K=0.20 for non plated steel fasteners and K=0.15 for plated fasteners.
When bolts are short for formula thread length, thread will extend as close to head or shoulder as practical. In actual production thread lengths may be longer than the formula thread lengths.

Tightening torque values are calculated from the formula T = KDP, where T = tightening torque, lb-in.; K = torque-friction 9,000. coefficient; D = nominal bolt diameter, in.; and P = bolt clamping load developed by tightening. lb. 5/8"-11 2. Clamp load is also known as preload or initial load in tension on 8,000.
