M8‑1.25 x 40 mm DIN 6921 Hex Flange Bolt – Class 8.8, Zinc Yellow, Non‑Serrated

The M8‑1.25 x 40 mm hex flange bolt is manufactured to DIN 6921 standards from metric Class 8.8 steel, delivering dependable strength and reliable fastening performance in industrial applications. Designed with a partial thread (PT) and coarse 1.25 mm pitch, it offers improved shear strength and effective load transfer for joints with a longer grip length. The non‑serrated integrated flange provides smooth, even load distribution, eliminates the need for a separate washer, and helps protect mating surfaces. Finished with a zinc yellow coating for enhanced corrosion resistance and easy visual identification, this bolt is ideal for automotive, machinery, and general industrial applications requiring durable and consistent clamping performance.
