Professional Applications & Engineering Value
The 10-24 UNC shoulder screw in 316 stainless steel addresses critical engineering challenges in precision machinery and industrial equipment. The black oxide finish provides additional corrosion protection while reducing galling during installation. With a Class 3A thread fit and coarse UNC threading, this fastener maintains consistent clamping force in high-vibration environments where loosening could cause equipment failure. The knurled socket head ensures positive tool engagement for reliable assembly in confined spaces. These shoulder screws are engineered for applications requiring precise axial positioning of rotating components, making them ideal for manufacturing equipment, automation systems, and transportation machinery where dimensional stability under load is paramount.
Specification Summary & Compliance
This precision shoulder screw features 10-24 UNC coarse threads with Class 3A fit tolerance for superior thread engagement. Manufacturing conforms to ASME B18.3 specifications, ensuring dimensional consistency across production lots. The component meets RoHS 3 (2015/863/EU) compliance for hazardous substance restrictions and REACH (EC 1907/2006) standards for chemical safety. Shoulder diameter maintains tight tolerance of -0.004" to -0.002" with shoulder length tolerance of -0.005" to 0.005" for precise assembly fitment.
