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 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.
12 Αυγ 2024 · Bolt Tightening Torque Chart: Standard Bolt Sizes at a Glance. Torque is a measure of the rotational force applied to an object, often expressed in units like Newton-meters (N m) or foot-pounds (ft-lb).
Because there are many variables that affect the torque-tension relationship, the only way to determine the correct torque is through experimentation under actual joint and assembly conditions. Bolt torque chart reference guides include Grade 2, B7, A307, A325, Grade 8, A490, and Grade 5.
26 Ιουν 2024 · Bolt torque chart. The following chart appears in the 2019 Atlas Copco Industrial Tools and Solutions catalog. It gathers the three required variables to understand and determine the maximum recommended torque for your bolt: bolt size, bolt grade and friction.
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.
