Our DIN 9021 washers are manufactured from \u003cstrong\u003eA4-70 grade 316 stainless steel\u003c\/strong\u003e, providing exceptional corrosion resistance and long term durability in marine, coastal, and industrial environments.\u003c\/p\u003e\n\u003cp\u003eDIN 9021 washers feature a \u003cstrong\u003elarge outside diameter with a precision sized center hole\u003c\/strong\u003e, allowing the load of a bolt or screw to be distributed over a much wider surface area. This prevents damage to wood, fiberglass, aluminum, plastics, and composite materials while also increasing the holding strength of the fastener.\u003c\/p\u003e\n\u003cp\u003eThese washers are commonly used anywhere material pull-through, vibration, or surface damage is a concern, including:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMarine hardware and deck fittings\u003c\/li\u003e\n\u003cli\u003eBoatbuilding and refits\u003c\/li\u003e\n\u003cli\u003eDock and marina construction\u003c\/li\u003e\n\u003cli\u003eSheet metal and aluminum assemblies\u003c\/li\u003e\n\u003cli\u003eFiberglass and composite structures\u003c\/li\u003e\n\u003cli\u003eWood joinery and carpentry\u003c\/li\u003e\n\u003cli\u003eIndustrial and mechanical installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eUnlike standard flat washers, \u003cstrong\u003eDIN 9021 fender washers provide a much larger bearing surface\u003c\/strong\u003e, making them ideal for thin materials, soft substrates, and slotted or oversized holes.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eWhy DIN 9021 Matters\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eDIN 9021 defines the \u003cstrong\u003eoutside diameter, inside diameter, thickness, and flatness\u003c\/strong\u003e of the washer so that it delivers consistent load distribution and proper fit. These are not oversized hardware store washers.
