HEAVY HEX BOLTS

Heavy hex bolts have a larger head than a standard hex bolt, measuring 1/8 of an inch larger than a finished hex bolt of the same diameter. To determine hex size, the formula is one-and-a-half times the diameter plus 1/8″.

Heavy hex bolts are generally specified for high temperature or high pressure applications, particularly where bolt heads will bear against flanges. Commonly used in a variety of high strength industrial applications such as steel fabrication and construction including bridges, highway structures and buildings.

Standard diameters are 1/2″ and larger.
