M12‑1.25 × 80 mm JIS B1189 Type 2 Hex Flange Bolt – Class 10.9, Zinc CR+3

The M12‑1.25 × 80 mm hex flange bolt is manufactured to JIS B1189 Type 2 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 an approximate 30–33 mm thread length, combined with a fine 1.25 mm pitch, it delivers improved shear strength and controlled load transfer where a longer unthreaded shank is required. The non‑serrated integrated flange ensures smooth, even load distribution while eliminating the need for a separate washer and helping protect mating surfaces, and the Zinc CR+3 coating offers corrosion resistance for automotive, machinery, and industrial assemblies requiring precision fit, durability, and consistent high‑strength clamping performance.
