5 1/2 inch length Hex Bolts (ASME B18. 2.1)

Hex Machine Bolts are threaded bolts with a hexagonal head on one end, with no washer face on the bearing surface and a threaded shaft on the other end. Hex bolts are tightened with a wrench and are used to connect metal parts. The body tolerances of hex machine bolts are not as close as those of hex cap screws. Hex machine bolts are covered under ASME Standard B18.2.1
