We are looking to replace fastener NAS 1008 1/2"-20, CRES, A-286 (UNS S66286) per AMS 5731, 140,000 PSI Min. These are used in wetted military marine environment, where galling, cross threading and fouling is a problem. We would consider a material substitution in the similar strength, and corrosion resistance (Inconel 686, ect). We are looking for a specification or recommendation for 1/2"-13 coarse thread fasteners.
