Professional Applications & Engineering Value
These 2-56 UNC rounded head screws in 316 stainless steel are engineered to address common industrial challenges, such as corrosion in marine, chemical, and outdoor settings. The passivated finish enhances the innate resistance of 316 stainless steel, preventing rust and extending service life in humid or corrosive conditions. With a coarse thread and fully threaded design, they provide rapid installation and robust clamping force in assemblies requiring frequent disassembly, like machinery panels, electronic enclosures, and automotive components. The Phillips drive ensures straightforward torque application, minimizing slippage and damage during fastening, making them a reliable choice for maintenance and production lines where efficiency and durability are critical.
Specification Summary & Compliance
This product features precise Class 2A thread fit and adheres to UNC thread standards with coarse spacing for consistent performance. Manufactured in compliance with ASME B18.6.3 specifications, it ensures dimensional accuracy and reliability. Additionally, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety and environmental compliance for industrial use.
