Professional Applications & Engineering Value
This zinc-plated steel flat head screw delivers critical engineering solutions where flush surface mounting and high tensile strength are paramount. The fully threaded UNC coarse spacing ensures superior holding power in wood, metal, and composite materials, while the 82° countersink angle provides seamless integration without protrusion. Ideal for industrial machinery, structural assemblies, and equipment manufacturing, the Rockwell B70 hardness and 60,000 psi tensile strength prevent stripping and deformation under heavy loads. The zinc plating offers essential corrosion protection in demanding environments, making these Class 2A thread fit screws a reliable choice for maintenance, construction, and manufacturing applications requiring durable, compliant fastening solutions.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 standards with Class 2A thread fit tolerance and UNC coarse thread spacing. Features include 5/16"-18 thread size, 6" length, and right-hand thread direction. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures safe, sustainable use across global industrial markets.
