Web bolt torque chart showing suggested torque values and corresponding bolt clamping forces for various sizes and specifications of fasteners. You can make ads in the engineering toolbox more useful to you! The bolt’s class indicates its material strength, with higher numbers meaning higher tensile and yield strength. Web button head cap screws. Web a193 b7 uses 75% of the yield strength. The load will be 90% of the bolt yield strength.
Remember, you may need to vary these numbers somewhat based on the individual joint or the amount of fastener lubrication. Torque values calculated from formula t=kdf. Web us recommended bolt torque. The prevailing torque lock nut clamp loads are listed at 75% of the proof loads specified for the appropriate grade bolt: 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. For dry bolts increase the torques with approximately 30%.
