I’m trying to calculate the clamping force resulting from torquing a nut and bolt to a particular level. I have found this formula in various forms in a lot of places. The bolt cross sectional area is critical to the prior calculation. Formulas and instructions for computing bolt preload and torque coefficient K (nut factor). Nut Factors are generalized averages that may vary greatly given all of the variables in any bolted joint, but are useful in approximating theoretical torque values. Preload, torque, joint stiffness, bolt stresses, and clamped part stresses are. Check out our bolted joint calculator based on the methodology described here.

Development of the bolt torque calculator has been done by using the theory given in the Machinery’s Handbook. Some of the key features of the calculator are. Introduction to the torques and tensions needed to fasten bolts. This calculator will calculate torque given the lead screw parameters and the. There are two torques the torque to raise the load and the torque to lower the. The equations that govern bolt loads can help engineers correctly size.

Measurements Verify Fastener Torque and Tension …. The stretch of a bolt or metal rod loaded in tension is calculated by use of the following equation. Use our bold load calculator to approximate your bolt load at installation. Calculate Bolt Load based on One of the following? Calculate direct shear load for both the weight and applied load (Fv) 4) Calculate Reaction Moment (M) at the bolt group centroid. For this reason, the tensile stress area is calculated through an empirical formula. A Page with information bolt joints.

The offset load is equivalent to a vertical force (F) + moment (F. R) at the centroid of the bolts. The shear stress in each bolt is calculated to ensure the design is safe. Values calculated using industry accepted formula T = KDP where T = Torque, K = torque coefficient (dimensionless), D = nominal diameter (inches), P = bolt.
