High Strength Stainless Steel Lock Nuts

Q: We are essentially having issue identifying the highest available high strength stainless steel nylon insert nuts. Is Duplex 2205 the best option?

A: If you are just looking for strength for your lock nut with a nylon insert, one of the highest strength stainless steel’s you could consider would be 17-4 PH (ranging from 136-190KSI)

A286 locknuts are a good option as well with good high temperature stability (130 KSI)

Duplex lock nuts are also much stronger than 316 with about 120KSI tensile strength. Duplex also offers better corrosion resistance. This material is not as strong as A286 or 17-4
