Product Description
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.
Enhanced Performance for Soft Materials
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.
