Professional Applications & Engineering Value

Engineered for demanding industrial applications, these M6 brass rounded head screws combine the natural corrosion resistance of copper alloy with precision metric coarse threading to solve common fastening challenges. The fully threaded hex drive design ensures maximum thread engagement in soft materials and blind holes, while the Rockwell B55 hardness provides excellent wear resistance in high-vibration environments. The 4mm hex drive allows for efficient installation in confined spaces, making these button head screws ideal for machinery, electrical enclosures, and marine equipment where corrosion resistance and reliable performance are critical.

Specification Summary & Compliance

This metric fastener features precision Class 6g thread tolerances per ISO standards with M6x1mm coarse thread spacing. The 20mm length fully threaded screw maintains consistent tensile strength throughout its engagement. Manufacturing complies with RoHS 3 (2015/863/EU) with exemption 6(c) for lead in copper alloy and REACH (EC 1907/2006) regulations, ensuring environmental compliance for global industrial distribution.
