ANSI ASME B18.2.1 Carbon Steel Heavy Hex Cap Screw
|
ANSI ASME B18.2.1 Carbon Steel Heavy Hex Cap Screw ManufacturingQBH Bolt manufactures heavy hex bolts from 3/8″ diameter through 3″ diameter in most ASTM, AASHTO, and SAE specifications. Special tooling can be created to produce nonstandard head dimensions or bolt heads with your company’s name and/or logo.
Several ASTM specifications require a hex head that is larger than a standard (finished) hex head. These specifications include: A193, A320 and A307B. Although A325 and A490 bolts also require a heavy hex head, please refer to Structural Bolts for dimensional specifications, since these bolts have shorter thread lengths than standard heavy hex bolts. ApplicationsHeavy hex bolts can be used for many different applications that include fastening wood, steel, and other construction materials for projects such as docks, bridges, highway structures, and buildings. Heavy hex bolts with forged heads are also commonly used as headed anchor bolts.
