Professional Applications & Engineering Value
These zinc-plated steel flat head screws are engineered to address common industrial challenges such as vibration loosening and corrosion. The UNC coarse thread and Class 3A thread fit provide superior holding power in materials like metal and hardwood, reducing the risk of strip-out under dynamic loads. The T10 Torx drive offers high torque capability, minimizing wear on tools and fasteners during repeated assembly. With a fully threaded design and 82° countersink angle, they ensure a secure, flush fit in pre-drilled holes, making them ideal for machinery, automotive, and electronics enclosures where reliability and a clean finish are critical.
Specification Summary & Compliance
This product features precise Class 3A thread fit per UNC standards with coarse thread spacing, ensuring tight tolerances for secure fastening. Manufactured in compliance with ASME B18.6.3 specifications, it also meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental and safety adherence for global industrial use.
