About Structural Bolts
Structural bolts are heavy hex bolts with a larger head, supplied as sets with heavy hex nuts and hardened washers. High strength friction grip (HSFG) bolts are tightened to a high preload so the joint carries load through friction between the steel plates.
We supply HSFG and structural bolt sets, black or hot dip galvanized, for steel fabricators and PEB contractors across India.

Structural Bolts FAQs
Why must HSFG bolts be used with hardened washers?
Hardened washers stop the nut and bolt head digging into the steel plate, so the preload is kept and the friction joint works as designed.
