WebAi = the area of the element in the plane normal to the bolt. Li = the thickness of the element. Where there is a change in area, e.g. through a flange, it may be assumed that the effective area grows along a 45º angle. Alternatively, the equivalent cylinder method [6] may be used to calculate the effective area. These methods are approximate. WebThe side of a thread surface connecting the crest and the root; Crest/top The top surface joining the two sides, or flanks. P = Pitch, mm or threads per inch (t.p.i.) The distance from a point on the screw thread to a corresponding point on the next thread measured parallel to the axis. β = The thread profile angle
