The screw thread on the external surface of cylinder or cone is called as the external thread. UTS (Ultimate tensile strength), often shortened to TS (tensile strength) or ultimate strength is the maximum stress that a material can withstand while being stretched or pulled before failing or breaking. In this online Thread Tensile Stress Area Calculator, the tensile stress area of the external thread is calculated based on the diameter and the number of threads per inch.

In this online Thread Tensile Stress Area Calculator, the tensile stress area of the external thread is calculated based on the diameter and the number of threads per inch.
At = (π/4) * (D -0.938194 * p)2
Where,
At = Tensile Stress Area (inch)
D = Diameter (inch)
n = Number of threads per inch
p = 1/n
Consider a screw of 0.5 inch diameter with 25 threads, find its tensile stress area.
At = (3.14/4) * (0.5 - 0.938194 * (1/25))2
= (0.785)* (0.5 - 0.03752776)2
= (0.785)* (0.46247224)2
= (0.785)* 0.2139
= 0.1679
Therefore, the thread tensile stress area is 0.1679 in2
