M6‑1.00 x 40 mm DIN 6921 Hex Flange Bolt – Class 10.9, Plain Finish, Non‑Serrated

The M6‑1.00 x 40 mm hex flange bolt is manufactured to DIN 6921 specifications from metric Class 10.9 steel, offering high tensile strength and dependable performance in demanding applications. Designed with a partial thread (PT) and coarse 1.00 mm pitch, it provides improved shear strength and effective load transfer where a longer unthreaded shank is required. The non‑serrated integrated flange ensures smooth, even load distribution, eliminates the need for a separate washer, and helps protect mating surfaces. Supplied in a plain (uncoated) finish, this flange bolt is ideal for machinery, automotive, and industrial assemblies used in controlled environments where high strength and precise clamping are required.
