Aerospace Fasteners & Aircraft Bolts

Superalloy fasteners engineered for jet engines, turbine discs, compressor casings, and airframe structures. Every bolt melted, forged, machined, and certified under one roof.

Which superalloy grades do aerospace fasteners use?

Aerospace fasteners operate at the extreme edge of materials science. From turbine disc bolts in the hot section at 700°C to compressor casing hardware that must resist thousands of thermal cycles, every part demands certified chemistry, precise heat treatment, and complete traceability. Our aerospace fastener manufacturing covers Inconel 718 to AMS 5662/5663, A-286 to AMS 5731/5732, Nimonic 80A for the hottest zones, and Inconel 625 for exhaust and ducting hardware.
