Professional Applications & Engineering Value
These 10-24 UNC flat head screws deliver critical engineering solutions where high tensile strength and corrosion resistance are paramount. The zinc-plated alloy steel construction provides durable protection against environmental factors in industrial settings, while the coarse thread spacing and Class 3A thread fit ensure secure fastening in metal assemblies, machinery, and structural applications. The partially threaded design concentrates clamping force precisely where needed, preventing joint loosening under vibration. With their 82° countersink angle and hex drive configuration, these screws enable flush mounting in predrilled holes while accommodating high installation torque, making them ideal for automotive, manufacturing, and heavy equipment applications requiring reliable, long-lasting fastening solutions.
Specification Summary & Compliance
These flat head screws feature 10-24 UNC coarse threads with Class 3A thread fit for precision engagement, manufactured to ASTM F835 specifications ensuring consistent quality and performance. The 1-1/2" length with 7/8" minimum thread length provides optimal fastening capability. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards confirms environmental responsibility and safety in industrial applications.
