Plain Grade 5 Heavy Hex Bolts

Grade 5 heavy hex bolts are externally threaded fasteners made of carbon steel. Bolts designated as heavy hex bolts are very similar to standard hex bolts however the head size across the flats and across the corners is larger providing a broader bearing surface.
Heavy hex bolts are one of the most common fasteners and can be used in a wide variety of applications. The 6-sided head makes them easy to install using a standard wrench or socket tool.
