This M24 x 90 High Strength Friction Grip (HSFG) Bolt and Nut set is manufactured in accordance with BS EN 14399-3 and is designed to deliver superior load-bearing capacity and friction-based shear transmission in structural steelwork. The bolt's performance surpasses that of standard bolts due to its unique tension-based operating principle.
Unlike conventional bolts that rely primarily on compression and shear through the bolt shaft, HSFG bolts are intentionally preloaded to induce clamping force between the connected plates. This pre-tension generates significant frictional force perpendicular to the bolt axis, which in turn transmits shear across the joint—making these bolts essential in steel structures where slippage must be avoided.
Supplied self colour (uncoated), this HSFG bolt and nut assembly is ideal for steel-to-steel connections in bridges, buildings, towers, and industrial frameworks. It delivers durability, strength, and compliance for demanding structural applications.
