M12‑1.75 x 90 mm DIN 6921 Hex Flange Screw – Class 8.8, Zinc CR+3, Partial Thread

The M12‑1.75 x 90 mm hex flange screw is manufactured to DIN 6921 standards from metric Class 8.8 steel, providing high tensile strength and reliable performance for demanding applications. Featuring a partial thread (PT) with a coarse 1.75 mm pitch, it is designed to improve shear strength and deliver effective load transfer in long clamping lengths. The non‑serrated integrated flange ensures smooth, even load distribution while eliminating the need for a separate washer and protecting mating surfaces, and the Zinc CR+3 finish offers corrosion resistance, making this fastener well suited for machinery, structural assemblies, automotive, and general industrial applications requiring durability and consistent clamping force.
