Professional Applications & Engineering Value
These zinc-plated steel flat head screws deliver exceptional performance in industrial applications where corrosion resistance, high tensile strength, and reliable fastening are critical. The T40 Torx drive provides superior torque transfer, minimizing tool slippage and damage during installation in machinery, structural assemblies, and heavy equipment. With UNC coarse threads and Class 2A fit, these screws ensure quick assembly and secure fastening in metals, plastics, and composite materials. The 82° countersink angle creates flush surfaces in pre-drilled holes, preventing protrusions in automotive, construction, and manufacturing applications where smooth finishes and vibration resistance are essential.
Specification Summary & Compliance
This fastener features 3/8"-16 UNC coarse threads with Class 2A thread fit for standard industrial applications. Manufactured to ASME B18.6.3 specifications with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The zinc-plated steel construction provides consistent dimensional accuracy with right-hand threading and standard flat head profile for reliable performance across various industrial applications.
