Professional Applications & Engineering Value

This 316 stainless steel shoulder screw is engineered to address critical challenges in precision machinery, automation, and assembly systems. The UNC coarse threads with Class 3A fit provide exceptional alignment and vibration resistance, minimizing loosening in dynamic operations. The 3/16" shoulder length and precise diameter tolerances allow for accurate positioning of components like gears, pulleys, or linkages, reducing wear and maintenance needs. With a hex socket knurled head, installation is swift and secure, even in confined spaces. Its high corrosion resistance and 70,000 psi tensile strength make it suitable for demanding sectors such as medical devices, marine equipment, and food processing, where durability and hygiene are paramount.

Specification Summary & Compliance

The screw adheres to UNC thread standards with a Class 3A thread fit for high precision, and shoulder dimensions include a diameter tolerance of -0.004" to -0.002" and length tolerance of -0.005" to 0.005". It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material reliability.
