Professional Applications & Engineering Value
Engineered for precision, these 2-56 UNC flat head Phillips machine screws excel in applications where space constraints and corrosion resistance are critical. The Black-Oxide 18-8 Stainless Steel construction prevents rust and oxidation, making them suitable for electronics, automotive components, and outdoor equipment. The fully threaded and coarse UNC thread design ensures rapid assembly and strong holding power in metals and plastics, reducing the risk of stripping. With an 82° countersink angle, they sit flush to avoid snagging and maintain aerodynamic or aesthetic surfaces. Ideal for industries requiring reliable industrial fasteners that meet stringent ASME B18.6.3 standards, these screws deliver consistent performance in high-stress environments.
Specification Summary & Compliance
This product features a Class 2A thread fit with UNC coarse threads and precise dimensions (e.g., 3/8" length, 0.162" head diameter). It conforms to ASME B18.6.3 manufacturing specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards for industrial use.
