Professional Applications & Engineering Value
These 2-56 UNC flat head screws are engineered to address common industrial challenges such as corrosion, high-stress conditions, and precise assembly requirements. Made from Black-Oxide 18-8 Stainless Steel, they provide exceptional resistance to rust and chemicals, making them suitable for outdoor, marine, and chemical processing equipment. The Phillips drive and Class 2A thread fit facilitate quick, secure installation in coarse-threaded applications, reducing assembly time and minimizing thread stripping. With a 100° countersink angle, these screws sit flush in materials, preventing snagging and improving aesthetics in electronics, machinery, and automotive assemblies. Their fully threaded design ensures uniform stress distribution, enhancing the longevity of critical connections in demanding environments.
Specification Summary & Compliance
This product features precise Class 2A thread fit with UNC coarse threads for reliable engagement, and dimensions including a 3/8" length and standard flat head profile. It meets ASME B18.6.3 specifications for consistency and performance, and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring no hazardous substances and adherence to environmental and safety standards in industrial fastener applications.
