It features a 13mm inside diameter and a 20.5mm outside diameter, with a 1mm thickness. Manufactured from Grade 18-8 Austenitic A2 stainless steel with an uncoated finish, this washer provides reliable corrosion resistance in a wide range of fastening assemblies. The external tooth design bites into both the mating surface and the fastener bearing face to resist loosening under vibration and dynamic loads. This item is sold in a minimum order quantity of 100 pieces per package, making it practical for shop stock or project-level quantities.\u003c\/p\u003e\n\u003cp\u003eThis lock washer is suited for use in mechanical assemblies, electrical enclosures, plumbing fixtures, HVAC equipment frames, and structural connections where M12 fasteners are used and vibration resistance is required. The 18-8 A2 stainless steel construction makes it appropriate for indoor and outdoor applications where mild to moderate corrosion exposure is a concern. Installers across plumbing, HVAC, electrical, and general mechanical trades use external tooth lock washers of this type when standard flat washers are insufficient to prevent fastener back-out.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExternal tooth design resists loosening under vibration and dynamic loads\u003c\/li\u003e\n  \u003cli\u003eGrade 18-8 Austenitic A2 stainless steel construction for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e13mm inside diameter sized for M12 fasteners\u003c\/li\u003e\n  \u003cli\u003e20.5mm outside diameter with 1mm thickness\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for direct use without additional treatment\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6797 and DIN 6798 standards\u003c\/li\u003e\n  \u003cli\u003eSold in a 100-piece minimum order quantity for efficient stocking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with M12 screws and bolts in applications requiring an external tooth lock washer.

Ensure the mating surface is clean and free of debris before assembly. Torque fasteners according to the fastener manufacturer specifications for the given material and application. Do not reuse lock washers that have been fully compressed, as tooth engagement may be compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 13mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 20.5mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Thickness\u003c\/strong\u003e: 1mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTooth Type\u003c\/strong\u003e: External Tooth\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 Austenitic Grade A2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 6797, DIN 6798\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.002 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: SEW7X1200-100BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720416264498,"sku":"SEW7X1200-100BX","price":9650.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ba6ca601a643ce5de8a71ffff5749778.jpg?v=1788563666","url":"https:\/\/voomisupply.com\/products\/value-collection-sew7x1200-100bx-m12-lock-washer-100-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
