Torque Calculator- this app is intended field estimation of a torque value based on stud size or nut size and lubrication. Simply enter a stud size or nut size and a lubricant and get a torque value.
Disclaimer; These figures are estimates based on ASTM A193 B7 studs at 70% yield and should be used as a guide only. For specific clamp load requirements consult the equipment manufacturer or the engineering department.
Bolted Joints and Torque- In a bolted joint the bolt is tightened to a calculated clamp load, usually by applying a measured torque load. The joint will be designed such that the clamp load is never overcome by the forces acting on the joint (and therefore the joined parts see no relative motion).
Foot pound (ft/lb) is a measurement of the rotational force necessary to tighten threaded fasteners. This calculator is designed to generate a torque measured in foot pounds (ft/lb) based on the size of the stud, the size of the nut and the lubrication.
Yield-A yield strength or yield point of a material is defined in engineering and materials science as the stress at which a material begins to deform plastically. Since 100% yield is a permanent deformation of the bolt this calculator is set a 70% of yield.
