Professional Applications & Engineering Value
This 316 Stainless Steel shoulder screw with Black Oxide finish addresses critical engineering challenges in precision assemblies. The 10-32 UNF fine thread and Class 3A thread fit minimize backlash and provide secure fastening in high-vibration environments like robotics, automotive, and machinery. The knurled socket head with hex drive allows for efficient torque application, reducing installation time while the corrosion-resistant material ensures longevity in humid or chemical-exposed settings. Its shoulder diameter of 1/4 inch and length of 1 1/8 inch offer precise pivot points and alignment in linkages, bearings, and electronic enclosures, enhancing overall assembly reliability and reducing maintenance needs.
Specification Summary & Compliance
This shoulder screw features a Class 3A thread fit with 10-32 UNF fine thread and shoulder diameter tolerance of -0.004" to -0.002" for high precision. It meets ASME B18.3 specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe and reliable use in global industrial applications.
