Professional Applications & Engineering Value

These blue-anodized 7075 aluminum socket head cap screws address critical engineering challenges in weight-sensitive applications where corrosion resistance and precision thread engagement are paramount. The UNC coarse thread configuration combined with Class 3A fit ensures reliable performance in high-vibration environments common to aerospace components, electronic enclosures, and precision instrumentation. The anodized surface treatment provides exceptional protection against oxidation and chemical exposure, while the 7075 aluminum alloy maintains structural integrity under stress without the weight penalty of steel alternatives. The standardized socket head design with 5/64" hex drive facilitates installation in confined spaces, making these fasteners ideal for maintenance-critical assemblies requiring frequent access.

Specification Summary & Compliance

Manufactured to precise dimensional standards with UNC 2-56 coarse threading and Class 3A thread fit tolerance for superior mating component engagement. The fully threaded 1/2" length provides consistent fastening capability along the entire shank. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring adherence to international substance restriction requirements for industrial components.
