Professional Applications & Engineering Value

These 10-24 UNC flat head screws deliver exceptional engineering value in applications where weight reduction and corrosion resistance are critical. The 2024 aluminum alloy construction provides significant advantages in aerospace, electronics, and transportation industries where every ounce matters. The fully threaded design ensures maximum holding power across the entire 1" length, while the 82° countersink angle creates clean, flush installations in precision machinery and enclosures. The UNC coarse threading with Class 2A fit prevents cross-threading during assembly, reducing installation errors and production downtime. These screws effectively solve common industrial challenges by combining lightweight durability with high tensile strength, making them ideal for applications requiring repeated disassembly and reassembly without compromising fastener integrity.

Specification Summary & Compliance

This flat head screw maintains precise dimensional accuracy with Class 2A thread fit per UNC standards and ASME B18.6.3 manufacturing specifications. The inch-system measurement ensures compatibility with North American industrial standards. Compliance includes RoHS 3 (2015/863/EU) for hazardous substance restriction and REACH (EC 1907/2006) for chemical safety, confirming environmental responsibility in industrial supply chains. The right-hand threaded, coarse-pitch design with standard flat head profile guarantees interchangeability and reliable performance in qualified applications.
