Professional Applications & Engineering Value

These M6 rounded head screws deliver critical engineering solutions where high tensile strength and reliable fastening are paramount. The zinc-plated alloy steel construction provides essential corrosion protection for machinery, equipment assemblies, and structural components exposed to industrial environments. The combination of Class 10.9 strength rating and Rockwell C32 hardness ensures these metric screws maintain integrity under vibration and dynamic loads. The flanged button head design eliminates the need for separate washers while providing superior clamping force distribution. With fully threaded coarse pitch configuration and 4mm hex drive, these industrial screws enable rapid installation in automotive, manufacturing, and heavy equipment applications where time efficiency and joint reliability are critical operational factors.

Specification Summary & Compliance

Manufactured to precise ISO 7380-2 standards with Class 6h thread fit tolerance ensuring consistent threading performance. The M6 x 1mm coarse thread configuration provides optimal engagement in various materials. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations guarantees safe use across industrial sectors. The 20mm length and 13.6mm flange diameter maintain dimensional accuracy for predictable performance in engineered applications.
