Fender washers feature a larger outside diameter relative to the inside diameter, distributing clamping load over a wider surface area and reducing the risk of pull-through in softer substrates. The 4.3 mm inside diameter accommodates M4 fasteners, while the 12 mm outside diameter provides a broad bearing surface. This washer meets DIN 9021 dimensional standards and uses metric sizing throughout. It is suited for general mechanical assembly, electrical enclosure work, HVAC panel fabrication, and light structural applications where corrosion resistance is a priority. Sold in a pack of 50.\u003c\/p\u003e\n\u003cp\u003eGrade 18-8 stainless steel makes this washer a practical choice for indoor and outdoor installations where exposure to moisture, mild chemicals, or humid conditions could cause carbon steel hardware to corrode. Typical applications include equipment mounting, sheet metal assembly, conduit and junction box work, and plumbing fixture installation. The plain finish means no coating to chip or flake in service. Tradespeople working in coastal environments, mechanical rooms, or food-adjacent spaces often specify 18-8 stainless hardware for longevity.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 18-8 stainless steel construction for corrosion resistance in wet or humid environments\u003c\/li\u003e\n  \u003cli\u003eFender-style large OD (12 mm) distributes load over a wider bearing surface than standard flat washers\u003c\/li\u003e\n  \u003cli\u003e4.3 mm inside diameter sized for M4 fasteners\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 9021 dimensional standard for metric fender washers\u003c\/li\u003e\n  \u003cli\u003ePlain finish with no coating to degrade or contaminate adjacent materials\u003c\/li\u003e\n  \u003cli\u003eSold in a convenient pack of 50\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with M4 metric fasteners in general mechanical, electrical, plumbing, and HVAC assembly applications requiring a DIN 9021 compliant fender washer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using hand tools appropriate for the fastener type; avoid over-torquing, which can deform the washer and reduce clamping effectiveness. Power down or de-energize any electrical assembly before adding or replacing hardware on live panels. When used in stainless-on-stainless assemblies, apply an anti-seize compound to threaded fasteners to prevent galling. Verify fastener grade compatibility before use in structural or pressure-rated applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWasher Type\u003c\/strong\u003e: Fender Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: M4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 4.3 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 12 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Plain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: DIN 9021\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A210022\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711755026738,"sku":"A210022","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/837bde83a05bce9f114cd669faf184fc.jpg?v=1788479244","url":"https:\/\/voomisupply.com\/products\/value-collection-a210022-m4-fender-flat-washer-50-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
