Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, these M12 hex head screws deliver exceptional performance where vibration resistance and structural integrity are critical. The zinc-plated steel construction provides reliable corrosion protection in manufacturing environments, while the Class 10.9 strength rating ensures consistent performance under high stress conditions. The extra fine 1.25mm thread pitch offers superior resistance to loosening in vibrating machinery, making these flanged hex screws ideal for automotive assemblies, heavy equipment manufacturing, and structural applications. The integrated flange design distributes clamping force evenly, reducing point stress and preventing surface damage to connected materials. With partial threading providing optimal grip length control, these fasteners maintain precise joint integrity in critical assemblies where reliability cannot be compromised.

Specification Summary & Compliance

This M12 x 1.25mm metric hex head screw features Class 6g thread fit tolerance for precision mating and JIS B 1189 Type 2 manufacturing specifications. The fastener maintains 55mm total length with 30mm minimum thread length and incorporates a 25mm flange diameter for optimal load distribution. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards ensures suitability for global industrial applications requiring restricted substance compliance. The Rockwell C32 hardness rating confirms consistent material properties throughout the manufacturing process.
