A washer is an element used in various types of agricultural machinery, including tractors, to provide adequate distance, support or protection for bolts, nuts or other fasteners. These washers play a key role in stabilizing connections and preventing loosening of elements during machine operation. They are made of durable materials that are resistant to corrosion and mechanical loads, which makes them an essential component in tractor mechanical systems. The use of appropriate washers affects the safety and longevity of agricultural machinery.
