About Heavy Hex Bolts
Heavy hex bolts are heavy-profile hexagon head bolts designed for use in structural applications, high-pressure piping, and heavy industrial machinery. Featuring a larger head than a standard hex bolt, they provide a greater bearing surface to distribute the clamping load more effectively. These bolts are typically coupled with heavy hex nuts and heavy washers to complete a high-strength bolting assembly.
At Jade Alloys, we produce heavy hex bolts with both full and partial thread configurations. Our range includes metric sizes from M12 to M36 and imperial sizes from 3/8" to 3", with the capability to customize up to M180 or 8" diameters. We offer a wide variety of thread profiles, including UNC, UNF, BSW, BSF, and metric coarse/fine.
As a specialized manufacturer, we utilize a variety of metals and alloys adhering to ASTM, ASME, ISO, DIN, and BS material specifications. Whether you require structural grade A325 bolts or high-temperature B7 alloys, our heavy hex bolts are engineered for durability and reliability in the most demanding environments.
