deformation. The proof load itself is usually 85% to 95% of a bolt’s yield strength, but the clamp load is significant because it is what ultimately provides the clamping pressure. Once the clamp load is determined, finding the correct torque value for a bolt is one simple calculation ...
This bolt torque calculator will ensure that you tighten up your bolts with the correct torque. Just as well, as a loose bolt can really ruin your day. Read on to discover what is bolt torque, the bolt tightening torque calculation formula, how to calculate bolt torque, and typical torque...
I need to use in calculation of Torque Value. In the formula of torque value calculation there is mention clamp load= 75 % of proof load So pls tell me from where we get this proof load value for bolt. Or give me the calculation of clamp load. Reply Dane McKinnon says: April 23...

Design resources for design screws and bolts for the proper torque, stress, strain, preload and other engineering critical design parameters. Torque and stress - strain calculation and formula
." The value of this factor indicates that harder, smoother, and/or slicker bolting surfaces, such as threads and bearing surfaces, require less rotational force (torque) to stretch (tension) a bolt than do softer, rougher, and stickier surfaces.The basic formula T =K x D x P stated...
On the basis of the plane hypothesis and the torque balance relationship the calculation diagram of the longitudinal bolt design calculation method is established, as shown in Fig. 5.51, and the maximum tensile stress σSM of the outermost row of longitudinal bolts is calculated as follows: Sign...
If the preload is achieved by an applied torque, the preload will be a function of the applied torque, the friction factor, and the diameter of the bolt. The preload is based on the strength of the material in tension and is limited to a specified allowable preload tensile stress as a ...
Manual Bolt Torquing is used to apply uniform torque to bolted connection by achieving the bolt load on even distribution. The torque value is manually set to apply to the bolted joints. The tool has an accuracy of +/-4% in a clockwise direction from 20 to 100% Max. torque and are te...
From the point of time the measured torque leads to a preset snag torque value, the advance amount of the rotational angle of the impact shaft 9 is measured, and when this rotational angle advance amount reaches an expected rotational angle preset value, supply power to an electric motor 2 ...
