To convert pounds (lbs) to Newtons (N), multiply by 4.448 To convert inches (in) to millimeters (mm), multiply by 25.4. Note: When using Zinc Plated (lubricated with wax) Top Lock Nuts, the K value can vary be-tween 0.12-0.16. For additional technical information, contact Fastenal Engineering at engineer@fastenal.com.
Bolt Torque Chart
Values calculated using industry accepted formula T = KDP where T = Torque, K = torque coefficient (dimensionless), D = nominal diameter (inches), P = bolt clamp load, lb. K values: waxed (e.g. pressure wax as supplied on high strength nuts) = .10, hot dip galvanized = .25, and plain non-plated bolts (as received) = .20.
Torque Table Standard Bolt Sizes SAE - Engineers Edge
Torque Table. The following suggested tightening torques provide an excellent starting point for determining torque requirements. Remember, you may need to vary these numbers somewhat based on the individual joint or the amount of fastener lubrication.
Use SAE 2, 5 or 8 values when grade is known, with a nut of sufficient strength. There is no difference in the above chart between the torque figures for fine or coarse threads. The torque figures
Bolt Torque Chart
Bolt Torque Chart showing suggested torque values and corresponding bolt clamping forces for various sizes and specifications of fasteners.
Bolt Torque Chart - AFT Fasteners
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, …
U.S. Recommended Bolt Torque Table. * Sizes from 4 to 10 are in in.-lbs. Sizes from 1/4 up are in ft.-lbs. ** Fine thread figures are for 1-14. Grade 2, 5, and 8 values are for plated bolts.
Bolt Torque Calculator
Jul 24, 2024 · Determine bolt size — find the diameter and thread pitch of the bolt. Look up torque specification — use a torque chart specific to the bolt's size and material. Consider material strength — adjust for the bolt and mating material's strength. Apply a torque wrench — set the wrench to the specified torque value.
US Bolt Torque Chart | Recommended Max Values | Fractory
Maximum tightening torques for US bolts. This chart displays values for lightly oiled threads. The tension is 70% of yield strength.
Bolt torque chart: the Atlas Copco guide
Jun 26, 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.
