M12‑1.25 × 50 mm JIS B1189 Type 2 Hex Flange Bolt – Class 10.9, Zinc CR+3

The M12‑1.25 × 50 mm hex flange bolt is manufactured to JIS B1189 Type 2 specifications from metric Class 10.9 steel, delivering high tensile strength and dependable fastening performance for demanding applications. Designed with a partial thread (PT) and an approximate 30–33 mm thread length, combined with a fine 1.25 mm pitch, it provides improved shear strength and controlled load transfer where an extended unthreaded shank is required. The non‑serrated integrated flange ensures smooth, even load distribution while eliminating the need for a separate washer and protecting 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.
