Professional Applications & Engineering Value
This 8-32 UNC shoulder screw is engineered to address critical alignment and stability challenges in precision machinery. The 316 stainless steel material offers excellent resistance to chemicals and moisture, making it suitable for medical devices, food processing equipment, and marine applications. Its ultra-low hex socket head minimizes protrusion, allowing seamless integration in tight spaces without compromising torque application. The precise shoulder fit with tight diameter and length tolerances ensures accurate component positioning, reducing wear and vibration in rotating assemblies like bearings, pulleys, and linkages. This combination of high tensile strength and corrosion resistance provides long-term reliability, minimizing maintenance downtime in industrial shoulder screw applications.
Specification Summary & Compliance
This shoulder screw features a Class 2A thread fit with UNC coarse threading, ensuring consistent engagement and ease of assembly. The shoulder maintains precise dimensions with a diameter of 3/16" (tolerance: -0.001" to 0") and length of 5/8" (tolerance: 0" to 0.002") for accurate alignment. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, it meets stringent environmental and safety standards for industrial components.
