Professional Applications & Engineering Value

Engineered for precision and reliability, these 6061 aluminum rounded head screws deliver exceptional value across multiple industrial sectors. The combination of UNC coarse threading and Class 2A thread fit ensures rapid assembly with minimal resistance, significantly reducing installation time in high-volume production environments. The flanged design eliminates the need for separate washers, providing superior clamping force distribution that prevents material deformation in delicate substrates. With full threading along the entire 3/4" length, these fasteners offer maximum adjustment flexibility and secure holding power in electronic enclosures, machinery panels, and automotive components. The hex drive system maintains torque integrity during installation, making them ideal for applications where vibration resistance and repeated access are critical requirements.

Specification Summary & Compliance

These rounded head screws feature precise 10-24 UNC coarse threads with Class 2A tolerance for consistent fit and performance. The manufacturing complies with RoHS 3 (2015/863/EU) standards under exemption 6(b)-II for lead as an alloying element in aluminum, and maintains full REACH (EC 1907/2006) compliance as of January 17, 2023. The 6061 aluminum construction meets industry standards for mechanical properties, including the specified 40,000 psi tensile strength and Rockwell B40 hardness rating.
