M12‑1.25 × 30 mm JIS B1189 Type 2 Hex Flange Bolt – Class 10.9, Zinc CR+3

The M12‑1.25 × 30 mm hex flange bolt is manufactured to JIS B1189 Type 2 specifications from metric Class 10.9 steel, providing high tensile strength and reliable fastening performance in demanding applications. Featuring a full‑thread (FT) design with a fine 1.25 mm pitch, it offers precise engagement and strong, consistent clamping force for high‑load or vibration‑prone assemblies. The non‑serrated integrated flange ensures smooth, even load distribution, eliminates the need for a separate washer, and helps protect mating surfaces, while the Zinc CR+3 coating delivers corrosion resistance for long service life in automotive, machinery, and industrial applications requiring accuracy, durability, and high‑strength fastening.
