Professional Applications & Engineering Value

These 6-32 UNC flat head screws are engineered to address common industrial challenges, such as corrosion in humid or chemical-exposed settings. The Black-Oxide 18-8 Stainless Steel construction provides a protective layer that combats rust and oxidation, extending service life in applications like machinery assembly, electronic enclosures, and automotive components. The coarse UNC threads and Class 2A fit ensure quick, secure fastening in metals and plastics, reducing installation time and minimizing thread stripping. With a fully threaded design and high 70,000 psi tensile strength, these screws deliver uniform clamping force, preventing loosening under vibration—critical for maintaining structural integrity in dynamic environments.

Specification Summary & Compliance

This product adheres to precise dimensional standards, including Class 2A thread fit and UNC coarse threading for consistent performance. It meets multiple industry specifications: Fed. Spec. FF-S-92, QQ-P-35, MS24693-24B, NASM24693, and SAE AMS2700. Additionally, it is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring environmental safety and regulatory adherence for global supply chains.
