Professional Applications & Engineering Value

These M10 flat head screws deliver critical engineering solutions for heavy-duty industrial applications where failure is not an option. The zinc-plated alloy steel construction provides essential corrosion protection while maintaining the Class 10.9 strength rating required for structural connections, machinery assembly, and equipment manufacturing. The fully threaded design ensures maximum engagement depth, distributing stress evenly along the entire 90mm length to prevent point loading and joint failure. With coarse 1.5mm pitch threading and Class 6g thread fit, these metric screws offer rapid installation while maintaining precise tolerance control. The hex drive system enables high-torque application without cam-out, making them ideal for automotive, construction, and manufacturing sectors where vibration resistance and long-term reliability are paramount.

Specification Summary & Compliance

Manufactured to DIN 7991 specifications with Class 6g thread tolerance ensuring dimensional accuracy and interchangeability. The metric coarse thread (M10x1.5) provides optimal performance in most materials while the 90mm length offers versatile application coverage. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations guarantees safe usage across international markets. The Rockwell C32 hardness rating confirms consistent material properties batch-to-batch, supporting quality assurance protocols in regulated industries.
