DIN 440 Washers for use in timber constructions
DIN Standards are issued for various components including industrial fasteners like Metric DIN 440 washers for use in timber constructions. DIN 440 large flat washers are manufactured from mild steel, zinc, low carbon steel, aluminum, and stainless steel A2 and A4. DIN 440 washers are available in a wide range of sizes, shapes, finishes, and materials. Based on the requirement, we also provide DIN 440 R – Flat washers for timber constructions and DIN 440 V – Square hole washers.
