Professional Applications & Engineering Value
This 316 stainless steel shoulder screw with black oxide finish provides critical solutions for precision machinery and industrial equipment. The UNC thread with Class 3A fit ensures secure fastening in high-vibration environments, while the precisely machined shoulder maintains accurate component alignment in rotating assemblies and bearing applications. The knurled socket head design allows for reliable torque application during installation and maintenance. Engineered for industrial shoulder screw applications requiring corrosion resistance and dimensional stability, this fastener delivers exceptional performance in manufacturing equipment, automation systems, and precision instruments where 10-24 thread size specifications are critical.
Specification Summary & Compliance
Manufactured to exacting standards with Class 3A thread fit and UNC thread specifications. The shoulder diameter maintains tight tolerance of -0.004" to -0.002" while shoulder length tolerance is held to -0.005" to 0.005". This shoulder screw complies with ASME B18.3 manufacturing specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
