Professional Applications & Engineering Value
Engineered for demanding industrial fastening applications, these brass flat head screws combine material advantages with precision manufacturing to solve critical assembly challenges. The corrosion-resistant brass composition prevents degradation in moisture-prone environments, while the UNC coarse threads and Class 2A thread fit ensure secure fastening in soft materials and vibration-prone settings. The 82° countersink angle provides flush mounting for aesthetic applications and moving components, with the slotted drive offering compatibility across maintenance toolkits. These fully threaded screws deliver uniform stress distribution in electronic enclosures, machinery panels, and precision instruments where 50000 psi tensile strength maintains joint integrity under operational loads.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 specifications with Class 2A thread fit tolerance for reliable engagement. Features UNC 2-56 coarse threads in right-hand direction with 1/2" length in inch system measurements. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across regulated industries.
