Non Standard Fine Thread Pitch High Accuracy Electropolished 316L Stainless Steel Self Locking Press Nut

Need fine pitch threads for precision adjustment or prevailing torque applications? We offer non-standard pitch customization, including M3x0.35 and M4x0.5 configurations. Featuring an electropolished 316L stainless steel surface with Ra≤0.4µm, these nuts are ideal for medical and food equipment applications. The all-metal self-locking structure provides high temperature resistance and eliminates contamination risks. 48-hour sampling available.

Standard coarse threads may not provide optimal performance for precision adjustment or high-vibration environments. Fine pitch threads offer smaller lead for finer positioning and superior self-locking properties. We accept any non-standard fine pitch customization—simply provide the pitch value or mating screw specification.

316L stainless steel is the low-carbon variant, minimizing sensitization after welding and offering enhanced intergranular corrosion resistance compared to standard 316. Electropolishing reduces surface roughness below Ra 0.4µm while removing micro-burrs and surface contaminants, meeting stringent cleanliness requirements for medical implants and food contact equipment. The all-metal self-locking structure (no nylon insert) withstands high-temperature sterilization processes such as autoclaving. Material certificates, roughness reports, and thread inspection reports are available. With 15 years of precision manufacturing experience, we specialize in solving unique thread requirements.
