Professional Applications & Engineering Value
These 2-56 UNC rounded pan head Phillips screws are engineered to address common industrial challenges such as corrosion, vibration loosening, and assembly speed. The Black-Oxide 18-8 Stainless Steel construction provides a durable barrier against moisture and chemicals, extending service life in applications like electrical enclosures, machinery assembly, and automotive components. The coarse thread design ensures quick engagement and strong holding power in softer materials or where rapid disassembly is needed. With a fully threaded shank and Class 2A thread fit, these screws deliver consistent clamping force and reduce the risk of strip-out, making them a reliable choice for high-strength, precision fastening in industrial and manufacturing settings.
Specification Summary & Compliance
This product features precise Class 2A thread fit per UNC standards, ensuring dimensional accuracy and interchangeability. It is manufactured in compliance with ASME B18.6.3 specifications for consistency and reliability. Additionally, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) requirements, confirming it is free from hazardous substances and suitable for environmentally conscious industrial applications.
