A286 Shoulder Bolts for High Temperature

Q: I need a shoulder bolt that will not change its shape at elevated temperatures. The bolt is near a mild carbon steel welding process and is under a small load. It is not in the heat affected zone, but it does see an elevated temperature. I am not sure exactly, but if we assume it sees 80% of the A 36 melting temperature, then we should be conservative. Any suggestions appreciated.

A: For elevated temperatures I would recommend an A-286 shoulder bolt. A-286 fasteners are known for their high strength, creep resistance and oxidation resistance at elevated temperatures. This material would be a significant improvement over carbon steel. A286 bolts will retain their strength to 1300°F .
