Your recently viewed items and featured recommendations. Parts are just part of what we do. When tightening a bolt, overcoming the friction at the threads causes torsional stresses through the bolt (the top twists more than the bottom) and so only the axial stress (tensile) of the bolt applies a clamping force. Once they know that, they can run the numbers based on fastener size and material to determine the required bolt stretch to achieve that clamp load. Part # 25424. Menu. 0000033311 00000 n The method is relevant to every fastener type though, so engineers need to keep re-evaluating in every situation to determine the best torque-angle combination.
