M6‑1.00 x 25 mm DIN 6921 Hex Flange Screw – Class 10.9, Zinc CR+3, Non‑Serrated

The M6‑1.00 x 25 mm hex flange screw is manufactured to DIN 6921 standards from metric Class 10.9 steel, providing high tensile strength and dependable 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 an 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, and the Zinc CR+3 finish provides corrosion resistance for long service life in automotive, machinery, and general industrial assemblies.
