Professional Applications & Engineering Value
This 5-40 UNC set screw delivers critical engineering value in precision assemblies where space constraints and reliability are paramount. The headless design and extended tip provide secure, flush mounting in tight spaces, preventing component slippage in high-vibration environments like machinery, automotive systems, and electronic enclosures. Manufactured from 18-8 stainless steel, it resists corrosion and maintains integrity in demanding conditions, while the Class 3A thread fit and coarse thread spacing ensure quick installation and robust clamping force. Ideal for industrial set screw applications requiring repeatable precision and compliance with ASME B18.3 specifications, this fastener minimizes maintenance and downtime.
Specification Summary & Compliance
This set screw adheres to Class 3A thread fit tolerances for precise engagement, with UNC coarse threading (5-40 size) and right-hand direction. It conforms to ASME B18.3 manufacturing standards and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe and sustainable use. Dimensions include a 1/8" length, 1/16" hex drive, and extended tip with specified diameter and length tolerances for consistent performance.
