Professional Applications & Engineering Value
This 2-56 UNC set screw delivers exceptional engineering value for precision assembly applications where space constraints and vibration resistance are critical concerns. The 18-8 stainless steel construction provides excellent corrosion resistance in demanding environments, while the cup point tip creates permanent locking by embedding into contact surfaces, preventing component slippage under heavy loads. The hex headless design allows installation in confined spaces where traditional fastener heads won't fit, making it ideal for machinery, automotive components, and precision instruments. With Class 3A thread fit and coarse UNC threading, this set screw maintains consistent clamping force in high-vibration industrial settings, solving common loosening problems that compromise equipment reliability and safety.
Specification Summary & Compliance
This set screw features precise Class 3A thread fit with 2-56 UNC coarse threading and 0.086" thread diameter, manufactured to exacting ASME B18.3 standards. The fastener maintains compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors. With 5/8" length and right-hand thread direction, this component delivers reliable performance in precision assembly applications requiring consistent dimensional accuracy and material integrity.
