Professional Applications & Engineering Value

This 17-4 PH Stainless Steel shoulder screw is engineered to solve critical alignment and durability challenges in industrial settings. The 4-40 UNC coarse thread and Class 3A fit provide a secure, vibration-resistant connection, essential for machinery, precision instruments, and automated systems. The 1/2" shoulder length with precise tolerances ensures accurate positioning of components like gears, pulleys, and bearings, reducing wear and misalignment. The hex socket drive and knurled head facilitate easy installation in confined spaces while preventing cam-out. With high tensile and shear strength, it withstands heavy loads and dynamic stresses, making it a reliable choice for aerospace, automotive, and high-performance manufacturing applications where failure is not an option.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 3A thread fit for high precision. The shoulder features a diameter of 1/8" (tolerance: -0.004" to -0.002") and length of 1/2" (tolerance: -0.005" to 0.005") for consistent performance. It is manufactured from hardened 17-4 PH Stainless Steel with a Rockwell C28 hardness. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety requirements for industrial use.
