The vVarious factors that decide the dimensions of thread bolts are grade mark, mechanical properties and nominal size range measured in inches. Tensile strength, yield strength and proof load are some of its mechanical properties and inch is the unit of their measurement. The bolt threadsthread bolts made of medium carbon steel has a nominal range of about 1/4 to 1 and 1/2. The tensile strength, yield and proof load of such varieties lie in the range of 60000, 36000 and 33000 respectively. The ones made of low carbon steel has mechanical properties almost same as the former but differs in their nominal range which is around 1/4 to 4.
