Heavy Hex Nuts
LOADSTAR Heavy Hex Nuts are high-strength structural nuts manufactured specifically to pair with HSFG bolt assemblies. With a larger bearing surface and greater width across flats compared to standard hex nuts, heavy hex nuts distribute clamping loads more uniformly across the joint — reducing the risk of surface damage and improving connection reliability in demanding structural applications.
