Flat washers distribute load across a fastened joint, reducing surface damage and preventing pull-through on bolted assemblies. This washer measures 21 mm inside diameter by 37 mm outside diameter and is 3 mm thick, conforming to DIN 125 and ISO 7089\/7090 fastener standards. With a hardness rating of 140 HV, it provides consistent performance in corrosive or marine environments where Grade 316 alloy offers superior resistance compared to Grade 304. Sold in packs of 10, this metric-series washer suits structural, mechanical, and industrial fastening applications.\u003c\/p\u003e\n\u003cp\u003eThis washer is intended for use with M20 metric fasteners in applications requiring corrosion resistance, such as marine hardware, chemical processing equipment, outdoor structural assemblies, and coastal construction. The plain finish keeps the washer free of coatings that could interfere with torque values or galvanic compatibility in stainless steel fastener assemblies. It is a standard choice for plumbers, pipefitters, millwrights, and general contractors working with metric hardware in wet or chemically aggressive environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 316 stainless steel construction for superior corrosion resistance in marine and chemical environments\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 125 and ISO 7089\/7090 fastener standards for metric flat washers\u003c\/li\u003e\n  \u003cli\u003e21 mm inside diameter sized for M20 screws and bolts\u003c\/li\u003e\n  \u003cli\u003e3 mm thickness provides solid load distribution across fastened surfaces\u003c\/li\u003e\n  \u003cli\u003e140 HV hardness rating for consistent performance under clamping loads\u003c\/li\u003e\n  \u003cli\u003ePlain finish with no coating, compatible with stainless steel fastener assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with M20 metric screws and bolts.

Always ensure the washer is seated flat against the mating surface before tightening to achieve proper load distribution. In stainless steel assemblies, apply an anti-galling compound to threaded fasteners to prevent seizing during torquing. Follow applicable mechanical or structural codes for the specific installation context.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWasher Type\u003c\/strong\u003e: Standard 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: 316\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: M20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 21 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 37 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Plain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 140 HV\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: DIN 125, ISO 7089, ISO 7090\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: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161807\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: A410360\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691963711794,"sku":"A410360","price":30.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ab7f91ec43aff47e124e772632440743.jpg?v=1788291489","url":"https:\/\/voomisupply.com\/products\/value-collection-a410360-m20-flat-washer-316-ss-10-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
