WebTorque has been converted into ft/lbs by dividing the result of the formula by 12. All calculations are for Coarse Thread Series (UNC). Grade 2 calculations only cover fasteners 1 ⁄ 4 “- 3 ⁄ 4 ” in diameter up to 6″ long; for longer fasteners the torque is reduced significantly. Clamp loads are based on 75% of the minimum proof loads ... WebThis calculator uses a practical starting point for all threaded fastener tightening analysis and uses the basic elastic torque-tension equation. ... This calculator may be used with any consistent units, e.g. torque = ft-lbs with ft, in-lbs with inches, N-mm with mm. Force is calculated consistent with units used. ...
