Calculate tightening torque, preload and surface pressure for hex head and socket head screws. Use our free online calculator!
A rule of thumb for regular dry screws is to use 0.2. For example, a torque of 40 in-lb on a 1/4" screw with clean dry threads (k = 0.2) will exert 800 pounds of clamping force! But did you notice how variable that pesky friction constant was? Simply adding a decent bolt lube...
