Professional Applications & Engineering Value
Engineered for precision and durability, these zinc-plated steel flat head screws address common industrial challenges such as corrosion, vibration loosening, and installation efficiency. The T15 Torx drive delivers exceptional torque transmission, preventing damage to the fastener and tool during high-stress applications. With UNC coarse threading and a Class 2A thread fit, they provide quick, reliable fastening in metals, plastics, and assemblies where disassembly is infrequent. The 82° countersink angle ensures a seamless fit in pre-drilled holes, reducing protrusion risks in machinery, electronics, and automotive components. Ideal for industrial applications requiring consistent performance, these screws combine material strength with compliant design to minimize downtime and maintenance costs.
Specification Summary & Compliance
This fastener features precise Class 2A thread fit and UNC coarse threading with a diameter of 0.164" and 3/8" length. It is manufactured in accordance with ASME B18.6.3 specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity for global supply chains.
