M8‑1.25 x 40 mm DIN 6921 Hex Flange Screw – Class 8.8, Zinc CR+3, Partial Thread

The M8‑1.25 x 40 mm hex flange screw is manufactured to DIN 6921 standards from metric Class 8.8 steel for high strength and dependable fastening performance. Designed with a partial thread (PT) and coarse pitch, it offers improved shear strength and efficient load transfer in longer assemblies. The non‑serrated integrated flange provides smooth, even load distribution while eliminating the need for a separate washer and helping protect mating surfaces. Finished with a Zinc CR+3 coating for corrosion resistance, this fastener is well suited for automotive, machinery, and general industrial applications requiring durability and consistent clamping force.
