Fasteners
Bolts, nuts, studs, screws and washers in high nickel alloys, copper and copper-nickel.
Overview
A fastener range built around high nickel grades
Bolting is often the first thing to fail on a corrosion-exposed joint. Our fastener range is built around high nickel alloys — Hastelloy, Monel, Inconel and commercially pure nickel — with copper and copper-nickel for seawater assemblies.
Both metric and inch threads are supplied. Sizes and head styles are confirmed on enquiry.
