Strong and corrosion resistant, KD Fasteners, Inc.’s Inconel Nylon 725 lock nuts are an excellent choice for seawater applications.

In fact, Inconel 725 hex nuts are twice the strength of Inconel 625 thanks to its heat treatment. Made with nickel, chromium, molybdenum, and niobium, Inconel 725 is an age-hardenable alloy that has essentially the same corrosion resistance as Inconel 625. Importantly, Inconel 725 is resistant to hydrogen embrittlement and stress-corrosion cracking as well as being incredibly tough.

 Inconel 725 Characteristics                                                                                                                      

  • Resistant to stress-corrosion cracking
  • Resistant to sea water
  • Excellent fracture toughness

When nylon inserts are added to the Inconel 725 lock nuts, they resist becoming loose due to vibration or shock loading. This addition makes them useful in a large variety of applications.
