Heavy head structural Fasteners (HSFG BOLTS) — engineered for the most demanding structural connections in transmission towers, buildings, bridges, refineries, and rail infrastructure.
Product Overview
Kaveri Industries manufactures heavy hex head structural bolts and screws, commonly specified as HSFG (High-Strength Friction Grip) bolts for critical structural connections.
Each bolt is produced to exacting dimensional tolerances and tested for proof load, hardness, and tensile strength — the hallmarks of zero-defect manufacturing that anchor our reputation with structural engineers and OEM procurement teams.
