M8‑1.25 × 40 mm JIS B1189 Type 2 Hex Flange Bolt – Class 10.9, Zinc CR+3

The M8‑1.25 × 40 mm hex flange bolt is manufactured to JIS B1189 Type 2 specifications from metric Class 10.9 steel, delivering high tensile strength and dependable performance in demanding fastening applications. Designed with a partial thread (PT) and a 22 mm thread length, combined with a coarse 1.25 mm pitch, it provides improved shear strength and efficient load transfer where an unthreaded shank is required. The integrated non‑serrated flange ensures smooth, even load distribution, eliminates the need for a separate washer, and helps protect mating surfaces. Finished with a Zinc CR+3 coating for corrosion resistance, this flange bolt is ideal for automotive, machinery, and industrial assemblies requiring precision fit, durability, and consistent high‑strength clamping performance.
