Alloy 600 Fasteners

Nickel Systems stocks hex bolts, hex nuts and washers, primarily 1/2″, 5/8″ and 3/4″ diameters. Other diameters are available by the order. We also have Alloy 600 socket head cap screws commonly used in the semiconductor industry on the shelf.

Alloy 600 is found in environments from cryogenic to those over 2000º F (1100º C). It is used extensively in furnace components. The chemical processing, electronics and semi-conductor industries make use of this material. Alloy 600 fasteners are valuable in the pulp and paper mills due to their resistance to abietic acid.
