The helical split design bites into the mating surface under load, resisting loosening caused by vibration or thermal cycling. With an inside diameter ranging from 20.2 to 21.2mm and a maximum outside diameter of 33.6mm, this washer is sized to seat correctly under an M20 fastener head or nut. Thickness is 4mm. Compliance with DIN 127 ensures dimensional consistency across the production run. Sold in packages of 10.\u003c\/p\u003e\u003cp\u003eThis washer is suited for mechanical assembly, structural fastening, and equipment maintenance applications where M20 fasteners are specified. The A2 stainless steel construction makes it appropriate for outdoor, marine-adjacent, or moderately corrosive environments where carbon steel hardware would be prone to rust. Maintenance technicians, millwrights, pipefitters, and general trade professionals will encounter this size in pump assemblies, pipe flanges, structural steel connections, and industrial equipment frames.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDIN 127 compliant metric split lock washer for M20 screw size\u003c\/li\u003e\n\u003cli\u003e18-8 austenitic stainless steel, Grade A2 -- corrosion-resistant in most non-chloride environments\u003c\/li\u003e\n\u003cli\u003eInside diameter 20.2 to 21.2mm, maximum outside diameter 33.6mm, 4mm thick\u003c\/li\u003e\n\u003cli\u003eHelical split profile creates spring tension that resists fastener back-out under vibration\u003c\/li\u003e\n\u003cli\u003eSold in a package of 10, minimum order quantity of 1 package\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DIN 127-standard split lock washer for use with M20 metric fasteners in any application requiring an 18-8 stainless steel helical lock washer at this size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall with the split ends biting into the bearing surface before torquing the fastener. Place the washer between the nut or bolt head and the mating surface -- not between a hardened washer and the part. Inspect for deformation before reuse; a washer that has been fully flattened has lost its locking function and should be replaced. Follow applicable torque specifications for the M20 fastener and joint class as defined by the design or maintenance specification for the equipment being serviced.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: M20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Inside Diameter\u003c\/strong\u003e: 20.2mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Inside Diameter\u003c\/strong\u003e: 21.2mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Outside Diameter\u003c\/strong\u003e: 33.6mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 4mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 18-8 Austenitic Stainless Steel, Grade A2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: DIN 127\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\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 47210\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709714596146,"sku":"47210","price":18.59,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1352b324ef4a0bb3f95b6a4909038db1.jpg?v=1788459483","url":"https:\/\/voomisupply.com\/products\/value-collection-47210-m20-split-lock-washer-18-8-ss-10pk","provider":"Voomi Supply","version":"1.0","type":"link"}
