Professional Applications & Engineering Value
This 4-40 UNC set screw delivers exceptional engineering value in precision assembly applications where space constraints and reliability are critical. The 18-8 stainless steel construction provides superior corrosion resistance for demanding environments, while the cup point design creates permanent seating that prevents component slippage under vibration. The headless hex drive configuration allows installation in confined spaces where traditional fasteners cannot fit, making it ideal for securing collars, gears, and pulleys on shafts. With Class 3A thread fit and coarse UNC threads, this fastener ensures quick assembly while maintaining precise alignment in machinery, automotive, and electronic applications where consistent clamping force is essential for operational safety and performance.
Specification Summary & Compliance
This precision set screw features 4-40 UNC coarse threads with Class 3A thread fit for superior dimensional accuracy. Manufactured to ASME B18.3 specifications, it ensures consistent quality and performance. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, containing no restricted substances. With a length of 1/8" and 0.050" hex drive size, this component meets industrial standards for reliable mechanical fastening applications.
