A similar approach is followed for the calculation of the tensile stress area: At = 0.7854 * [d - (0.9743 / n)]2, where d is given in inches, and n is given in threads/inch. Reference: Machinery's Handbook published by Industrial Press. The table below provides the nominal bolt diame...
The value for tensile stress area can be determined from: As = π/4 x (D - (.938194 x p))² Where: D: bolt diameter p: 1/threads per inch (TPI) Clamp load is typically around 75% of a bolt’s proof load; that is, the highest stress the bolt can accommodate before experienci...
@Chano- In a straight line pull, the length of the bolt is irrelevant. The breaking point is the tensile stress area multiplied by the minimum tensile in psi. If your joint is more complicated, and if there are forces that are not in a straight line, then you will need to consult an...
Shear Calculation on 304 (A2-70) Bolt First of all let us consider the basic UNF threadform : First Pass : consider the traditional STRESS AREA of the thread under TENSILE loading (As) : Second Pass : consider the first Turn of Thread Loading ONLY : There is a widespread assumption that...
Note!- be aware that this is a rough calculation where the screw pitch is not included. Typical Metric and Imperial bolt torques are indicated in the links below: Metric Bolts - Tightening Torques US Bolts - Tightening Torques Manufacturing data should always be checked before use. ...
F = Preload Tension Force At = Tensile Shear Area of Bolt Sp = Proof Load of Bolt (or some percentage less than 100% of yield load of bolt, typically 85 % of yield Sy) c = 0.75 For connections requiring reuse c = 0.89 For permanent connections ...
