High-Temperature Alloy Fasteners (A286, Inconel)

A286, Inconel 718, Waspaloy, MP35N and 17-4PH bolts, nuts and studs for heat and corrosion.

Overview

Where steel bolts lose strength or corrode, superalloy fasteners keep their clamp. A286 is the workhorse to about 650 °C and is non-magnetic. Inconel 718 gives higher strength in the same range, and Waspaloy goes hotter still. MP35N combines very high strength with corrosion resistance.

These alloys are used beyond aerospace too: gas turbines, exhaust systems, motorsport, oil and gas, and chemical plants. We supply aerospace-standard parts and metric parts made to drawing.

Common AN, MS and NAS sizes in alloy steel and stainless steel are usually available ex-stock in India. Superalloy, titanium and special NAS parts are imported for you from AS9120-certified distributors, with certificate of conformity, mill test reports and full lot traceability. Ask us for current stock and lead time.
