Reliability: Once tightened, Bolts will remain tight and maintain the permanent strength of the joint, Absence of heavy stress concentration due to absence of bearing between bolts and plates.
Economy: Fewer high strength bolts are required than M.S. bolts and rivets. Drilling of close holes is not required. Overall weight the structure will be very light.
Simplicity: A minimum of skill is required in tightening and the operators need only to follow a few simple rules.
Convenience: Whether in the workshop or at site, H.S.S bolts enable joints to be made easily. Welding of site splices can be eliminated, avoiding difficulties of welding in adverse weather conditions. Absence of pneumatic, hammers used in riveted joints reduce noise level considerably.
