M6‑1.00 x 40 mm DIN 6921 Hex Flange Screw – Class 8.8, Zinc CR+3, Partial Thread

The M6‑1.00 x 40 mm hex flange screw is manufactured to DIN 6921 specifications from metric Class 8.8 steel for strong and reliable fastening performance. Designed with a partial thread (PT) and coarse pitch, it offers improved shear strength and effective load transfer in longer assemblies. The non‑serrated integrated flange provides smooth, even load distribution while eliminating the need for a separate washer. Finished with Zinc CR+3 plating for corrosion resistance, this screw is ideal for automotive, machinery, and general industrial applications requiring durability and consistent clamping force.
