Professional Applications & Engineering Value
This 316 stainless steel shoulder screw is engineered to address critical challenges in precision machinery, automation systems, and corrosive environments. The 10-32 UNF fine thread and Class 3A thread fit provide excellent resistance to loosening under vibration, making it ideal for dynamic assemblies in robotics, aerospace, and medical equipment. The knurled socket head ensures secure tool engagement, reducing slippage during installation. With its corrosion-resistant properties and robust 70,000 psi tensile strength, it offers reliable performance in applications requiring repeated disassembly, high humidity, or exposure to chemicals, while the precisely machined shoulder maintains alignment in rotating parts and bearing mounts.
Specification Summary & Compliance
This shoulder screw features a Class 3A thread fit with a 10-32 UNF fine thread, ensuring tight tolerances and secure fastening. The shoulder diameter is 1/4" with a tolerance of -0.004" to -0.002", and the shoulder length is 1/2" with a tolerance of -0.005" to 0.005". Manufactured in compliance with ASME B18.3 specifications, it also meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, guaranteeing safety and regulatory adherence for industrial use.
