Professional Applications & Engineering Value
This 2-56 UNC set screw delivers critical engineering advantages in demanding applications where space constraints and vibration resistance are paramount. The headless design allows flush mounting in tight assemblies, while the coarse thread spacing provides rapid installation in production environments. Manufactured from 18-8 stainless steel, it offers excellent corrosion resistance for outdoor equipment, marine components, and food processing machinery. The cup tip configuration creates concentrated contact pressure, preventing shaft slippage in power transmission systems and precision instruments. These industrial set screws are particularly valuable in aerospace subassemblies, automotive controls, and electronic enclosures where Class 3A thread fit ensures zero backlash in critical positioning applications.
Specification Summary & Compliance
This precision fastener maintains Class 3A thread fit tolerances per UNC standards with 2-56 thread size and right-hand thread direction. Manufacturing conforms to ASME B18.3 specifications, ensuring dimensional accuracy and performance reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global supply chains and regulated industries.
