These Form A Flat Washers are manufactured from A4 (316) grade stainless steel and conform to DIN 125A standards, offering a reliable and durable solution for a wide range of fastening applications. Known for their marine-grade corrosion resistance, these washers are ideal for use in harsh environments including coastal, chemical, or food-grade installations.
Form A washers are the most commonly used flat washer type, providing a smooth bearing surface to distribute loads and protect the surfaces of materials during fastening. The increased outer diameter helps reduce wear, prevents pull-through, and offers extra support when tightening nuts or bolts onto soft materials or oversized holes.
Whether used in general construction, engineering, marine, or industrial environments, A4 stainless Form A washers ensure long-lasting protection and performance. Available in a comprehensive range of metric sizes to suit standard bolts and threaded fasteners.
