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.
Torque-Tension Relationship for A307A, Grade 5, 8 & 9 Bolts. The torque values can only be achieved if nut (or tapped hole) has a proof load greater than or equal to the bolt's minimum ultimate tensile strength. Clamp load calculated as 75% of the proof load when specified by the standard. ASTM A307 utilized 75% of 36,000 PSI.
SAE GRADE 8. Fine Thread. 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.
The torque values can only be achieved if nut (or tapped hole) has a proof load greater than or equal to the bolt's minimum ultimate tensile strength. Clamp load calculated as 75% of the proof load when specified by the standard.
5/8 - 11 UNC : Basic Thread Dimensions (Pitch, minor & major diameters, depth, lead), Tolerance range for all applicable classes and much more.
Metric Fine Thread Bolt Torque. The following table shows the tightening torque for metric fine thread fasteners. In the List you find the metric fine torque unit in Nm and ft lbs. You can also made an conversion from the unit Nm to ft lbs and also from ft lbs to Nm.
For J429 Grade 5 and 8, H-K 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. A193 B7 uses 75% of the yield strength.
