M12‑1.75 x 45 mm DIN 6921 Hex Flange Bolt – Class 10.9, Plain Finish, Non‑Serrated

The M12‑1.75 x 45 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 demanding applications. Designed with a partial thread (PT) and coarse 1.75 mm pitch, it offers improved shear strength and efficient 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. Supplied in a plain (uncoated) finish, this flange bolt is ideal for machinery, automotive, and industrial assemblies used in controlled environments requiring high strength and precise clamping.
