Professional Applications & Engineering Value
This 6-80 ultra fine thread set screw delivers exceptional value in precision engineering applications where space constraints and vibration resistance are critical. The 303 stainless steel body offers excellent machinability and corrosion resistance, while the Class 3A thread fit ensures tight tolerances for secure fastening in sensitive equipment. The ball tip design with alloy steel tip provides concentrated contact pressure without damaging shaft surfaces, making it ideal for positioning components in machinery, optical instruments, and electronic enclosures. The headless configuration with 5/64" hex drive enables installation in confined spaces where traditional fasteners can't be used, solving common assembly challenges in aerospace, medical device manufacturing, and precision instrumentation.
Specification Summary & Compliance
This precision fastener features 6-80 UNS ultra fine threads with Class 3A thread fit for exacting dimensional requirements. The 3/8" length and 0.138" thread diameter provide consistent performance in precision assemblies. Manufacturing complies with RoHS 3 (2015/863/EU) with exemption 6(c) for lead in copper alloy and REACH (EC 1907/2006) standards, ensuring environmental responsibility while maintaining mechanical integrity for industrial applications.
