- Full regulatory compliance meeting ASME B18.3, RoHS 3, and REACH standards for global industrial use
Professional Applications & Engineering Value
Engineered for precision machinery and industrial equipment, this 2-56 UNC set screw delivers critical fastening solutions where space constraints and vibration resistance are paramount. The Black-Oxide Alloy Steel construction provides superior corrosion protection in manufacturing environments, while the Class 3A thread fit maintains tight tolerances for secure positioning of gears, pulleys, and collars on shafts. The cup point design bites into mating surfaces, preventing rotational slip in high-torque applications. With Rockwell C45 hardness and coarse thread spacing, these headless set screws withstand repeated adjustments without thread degradation, making them ideal for maintenance-intensive industrial settings.
Specification Summary & Compliance
This 2-56 UNC set screw features precision Class 3A thread fit with right-hand coarse thread spacing, manufactured to ASME B18.3 specifications (ASTM F912). The 5/32" length and 0.086" thread diameter maintain dimensional accuracy for consistent performance. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards ensures suitability for global industrial applications requiring restricted substance control.
