M20‑2.50 x 80 mm DIN 6921 Hex Flange Bolt – Class 10.9, Plain Finish, Non‑Serrated

The M20‑2.50 x 80 mm hex flange bolt is manufactured to DIN 6921 specifications from metric Class 10.9 steel, providing high tensile strength and dependable fastening performance for heavy‑duty applications. Designed with a partial thread (PT) and coarse 2.50 mm pitch, it delivers improved shear strength and efficient load transfer for assemblies requiring a longer grip length. 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, structural, automotive, and industrial assemblies used in controlled environments where high strength and precise clamping are required.
