Professional Applications & Engineering Value
These 7/16"-14 UNC flat head screws deliver critical performance in demanding industrial assemblies where reliability is paramount. The zinc-plated alloy steel construction provides excellent corrosion protection for machinery, structural frameworks, and outdoor equipment. With 130,000 psi tensile strength and Class 3A thread fit, they maintain integrity under extreme vibration and load conditions common in manufacturing and construction. The 82° countersink angle ensures flush mounting in predrilled holes, preventing snagging while maintaining aerodynamic or aesthetic surfaces. These fully threaded fasteners offer maximum engagement in metal-to-metal applications, reducing the risk of loosening in high-stress environments.
Specification Summary & Compliance
Manufactured to precise UNC coarse thread specifications with Class 3A fit for superior thread engagement. Complies with ASTM F835 mechanical and dimensional requirements, ensuring consistent quality and performance. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for safe use across global markets. Features standard right-hand threading and 1" length with complete threading for uniform stress distribution.
