M6‑1.00 x 40 mm DIN 6921 Hex Flange Screw – Class 10.9, Zinc CR+3, Non‑Serrated

The M6‑1.00 x 40 mm hex flange screw is manufactured to DIN 6921 standards from metric Class 10.9 steel, providing high tensile strength and reliable fastening performance for demanding applications. Designed with a partial thread (PT) and coarse 1.00 mm pitch, it offers improved shear strength and effective load transfer where a longer unthreaded shank is preferred. The non‑serrated integrated flange ensures smooth, even load distribution while eliminating the need for a separate washer and helping protect mating surfaces. Finished with a Zinc CR+3 coating for corrosion resistance, this flange screw is ideal for automotive, machinery, and general industrial assemblies requiring strong, consistent clamping force and long service life.
