Fender washer M12 DIN 9021 zinc (box) (pack 30 pcs) STROYMETIZ UTORM3070073

DIN 9021 oversized body washer is a type of fastener used together with bolts, screws, and nuts for fastening in various industries, construction, machine building, automotive, and the national economy. It is a traditional round flat washer, but DIN 9021 is characterized by an outer diameter three times larger than the inner diameter, which allows for the distribution of the clamping load and reduces specific pressure on the material without damaging it. When used with metal, it provides greater friction and holds the connection assembly against any displacement and can withstand increased vibration loads. Due to these properties, it is commonly referred to as a body washer. Stainless steel washers are made of A2 grade steel, which allows them to be used in extreme conditions, such as chemical and marine environments or at elevated temperatures.
