Professional Applications & Engineering Value
This 8-32 UNC shoulder screw in 316 stainless steel is engineered to address critical challenges in precision assemblies, such as misalignment and component wear. The 2" precision shoulder provides a stable bearing surface for rotating parts like gears and pulleys, reducing friction and extending equipment life. Its coarse thread design and Class 3A thread fit ensure quick, secure fastening in high-vibration environments, from industrial machinery to automotive systems. The knurled head and hex drive facilitate easy handling with standard tools, while the corrosion-resistant properties make it suitable for marine, chemical, and outdoor applications where durability is paramount.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 3A thread fit for high precision. Key dimensions include a thread size of 8-32, shoulder diameter of 3/16" (tolerance: -0.004" to -0.002"), and shoulder length of 2" (tolerance: ±0.005"). It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met for industrial use.
