Root area of bolt
WebQuestion 1 When a bolt is in tension the load on the nut is transmitted through the root area of the bolt which is smaller than the shank area. An ISO metric bolt 24 mm in diameter (root area = 353 mm?) carries a tensile load. WebApr 12, 2010 · Root area is based on the root diameter of the threads, and therefore its stress area is smaller than the tensile stress area. Root area is not based on experimental …
