Academia edu is a platform for academics to share research papers tensile strength by its tensile stress area As Determining the strength of the threads is more complicated Since the male threads pull past the threads or vice versa the threads fail in shear and not in tension Therefore the stripping strength of an assembly depends on the shear strength of the nut and bolt materials ASME SA307 Threaded Rod amp Anchor Bolt manufacturer in India see astm a307 bolt dimensions and shear strength ASTM A307 Bolts are specified to have carbon steel and in the range of 188 inches to 4 inches of diameter There are three major grades as A B and C in this specification often made from the A36 round bars 55780 5 17 2 154000 69900 1 The maximum loads in the table above are based on allowable tensile stress of 12 kpsi reduced by 25 to 9 kpsi allowable stress 1 kg 9 81 N Threaded Rods Proof Load Capacities in Metric Units Mass and Weight the difference Fine and extra fine threads can be examined together Their smaller pitches and greater TPI equate to better tensile strength and a larger minor diameter provides better shear strength Smaller thread helix angles also provide superior resistance to vibration in fine threaded fasteners a very important consideration
