Made from Grade 18-8 stainless steel, it provides corrosion resistance in wet, outdoor, and chemically exposed environments. The washer measures 21mm inside diameter, 37mm outside diameter, and 3mm thick, conforming to DIN 125, ISO 7089, and ISO 7090 dimensional standards. It distributes clamp load across the bearing surface, reducing fastener pull-through and protecting the mating material. Machinists, maintenance mechanics, pipefitters, and structural assemblers use this washer in metric bolted connections across industrial, commercial, and marine applications.\u003c\/p\u003e\n\u003cp\u003eThis flat washer suits M20 bolted assemblies in general industrial fabrication, equipment mounting, structural framing, and plumbing or mechanical system installations where metric fasteners and corrosion resistance are required. The 18-8 stainless steel construction makes it appropriate for both indoor and outdoor service conditions, including environments with moisture or mild chemical exposure. It follows the DIN 125 and ISO 7089\/7090 fastener standards, making it compatible with metric hardware in compliant assemblies worldwide.\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 and outdoor environments\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 125, ISO 7089, and ISO 7090 dimensional standards\u003c\/li\u003e\n  \u003cli\u003e21mm inside diameter sized for M20 fasteners\u003c\/li\u003e\n  \u003cli\u003e37mm outside diameter and 3mm thickness for broad load distribution\u003c\/li\u003e\n  \u003cli\u003eHardness rated at 140 HV for reliable clamping without deformation under load\u003c\/li\u003e\n  \u003cli\u003eMetric system of measurement for use in globally standardized bolted 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 in assemblies conforming to DIN 125, ISO 7089, and ISO 7090 fastener standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall by a qualified mechanic or assembler following applicable torque specifications for the fastener grade and joint design. Ensure the washer seats flat against the mating surface with the fastener centered through the 21mm bore before tightening. Do not mix stainless steel washers with carbon steel fasteners in environments prone to galvanic corrosion without evaluating material compatibility. Inspect washers for deformation or surface damage before reuse in critical joints.\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: 18-8 Stainless Steel\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: 21mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 37mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3mm\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\u003eWeight\u003c\/strong\u003e: 0.1 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: 125-20-A2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720899920178,"sku":"125-20-A2","price":1003.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b4d7384f35dc096a12b16a6034eec5dd.jpg?v=1788570696","url":"https:\/\/voomisupply.com\/products\/value-collection-125-20-a2-m20-standard-flat-washer-18-8-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
