Details for Socket screw head size, Hex key or wrench drive size, hardness and tensile strengths for screws including Button Head, Socket Head Cap, Low Head Socket, Set Screws and Flat Head socket screws. The bolt’s class indicates its material strength, with higher numbers meaning higher tensile and yield strength. T = wrench torque (Nm, lb f ft) K = constant that depends on the bolt material and size . T = K F d (1 - l / 100) (1) where . 14, Fine thread and course threads apply 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. 7 7. As well as where a bolt is screwed into a weak part, another important reason for reducing the torque setting of a nut and bolt is if the bolt is carrying other loads. The following table shows the tightening torque for metric fine thread fasteners. K = 0. In the List you find the metric fine torque unit in Nm and ft lbs.
