Designation of bolts:
∴ M 36 × 4 means the nominal diameter of the bolt is 36 mm and pitch is 4 mm
The load P lifted by a bolt with failing is given by,
where dc is the Nominal diameter of the thread in mm or m, and σt is the tensile stress of the bolt in MPa.
Calculation:
Given:
Tensile stress σt = 280 MPa ,FOS = 2
Load on the bolt
