Socket Head Cap Screw

Socket head cap screws are often used in assemblies with counterbored holes. The head height is equal to the nominal diameter. For sizes 1/4″ and larger, the head diameter is equal to one-and-a-half times the nominal diameter. Nickel Systems maintains an inventory of socket head cap screws in Hastelloy® C276 (Alloy C276) in both inch and metric sizes. Most sizes 1/2″ diameter and larger, are fully threaded. Current inventory in socket head cap screws includes Duplex 2205, A286, Carpenter® 20 (Alloy 20), Nitronic® 60 (Alloy 60), 310 Stainless, 330 Stainless, 17-4 PH, 18-8 Stainless and 316 Stainless.

These screws require less maintenance and deliver quality service for a long period of time. The Screws we offer are widely used in various industries like Construction and other manufacturing units.
