M6‑1.00 × 40 mm JIS B1189 Type 2 Hex Flange Bolt – Class 10.9, Zinc CR+3

The M6‑1.00 × 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 for demanding applications. Designed with a partial thread (PT) and a specified 18 mm thread length, along with a coarse 1.00 mm pitch, it provides improved shear strength and controlled 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 precision industrial assemblies requiring high strength, accurate fit, and consistent clamping performance.
