Descripción de producto
Precipitation Hardened High Fatigue Life Custom Ring Groove 17-4PH Stainless Steel Self Locking Nut
17-4PH Stainless Steel Self Locking Nut with Custom Ring Groove for High Fatigue Applications. Under high-fatigue conditions, ordinary self-locking nuts have insufficient life. Our 17-4PH precipitation hardened self-locking nuts are H900 heat treated to 1300MPa tensile strength, specifically designed for dynamic loading. Custom ring groove allows snap ring installation for secondary locking. Ideal for robot joints, racing suspension, drone rotor mechanisms. 48hr sampling.
Enhanced Performance for Soft Materials
In robot joints, racing suspension, or high-speed rotating mechanisms, fasteners endure frequent tension-compression cycles and vibration. Ordinary stainless steel self-locking nuts may loosen after millions of cycles due to fatigue. 17-4PH precipitation hardened stainless steel, through H900 aging treatment, achieves ultra-high strength while maintaining good toughness, with fatigue limits far exceeding 304 or 316.

We offer custom ring groove service: you specify groove position, width, and depth for installing a snap ring or retaining ring, providing mechanical backup locking—even if the self-locking feature fails, the nut will not come off. This dual locking design has been proven in aerospace and racing applications. 17-4PH also offers good corrosion resistance, comparable to 304. Fatigue test data is available upon request. 15 years experience—providing the most reliable locking for your dynamic mechanisms.
