The helical split design bites into the fastener and mating surface under torque load, resisting loosening from vibration and dynamic loading. Inside diameter ranges from 0.220 to 0.227 inches, maximum outside diameter is 0.377 inches, and thickness is 0.056 inches. The zinc yellow dichromate coating provides moderate corrosion resistance suitable for general industrial and mechanical applications. Each package contains 250 washers. Installation requires no special tools beyond standard hand or power fastening equipment.\u003c\/p\u003e\n\u003cp\u003eThis split lock washer is suited for mechanical assembly, light fabrication, equipment maintenance, and general fastening work where a Number 12 screw is used. Typical applications include panel assembly, electrical enclosures, HVAC equipment mounting hardware, and equipment frames where vibration resistance is needed at the fastener joint. The inch-system dimensions make this washer a direct fit for standard imperial Number 12 fastener installations across residential, commercial, and light industrial settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAISI 4037 alloy steel construction for strength in high-torque fastening applications\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish for moderate corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eHelical split design resists fastener backout under vibration\u003c\/li\u003e\n  \u003cli\u003eInside diameter 0.220 to 0.227 inches for consistent Number 12 screw fitment\u003c\/li\u003e\n  \u003cli\u003e0.056-inch thickness provides reliable spring tension without excessive stack height\u003c\/li\u003e\n  \u003cli\u003ePack of 250 units supports production, maintenance, and bulk repair work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Number 12 inch-system screws and bolts in standard imperial fastener assemblies across mechanical, electrical, and HVAC applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall between the fastener head or nut and the mating surface with the split ends oriented to bite on final tightening. Ensure the mating surface is clean and free of burrs before assembly. Do not reuse split lock washers that have been fully compressed flat, as they will not provide effective locking force. No special certifications or regulated codes govern general split lock washer installation, but follow applicable equipment manufacturer torque guidelines for the fastener being used.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: Number 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: AISI 4037\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Zinc Yellow Dichromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Inside Diameter\u003c\/strong\u003e: 0.220 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Inside Diameter\u003c\/strong\u003e: 0.227 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Outside Diameter\u003c\/strong\u003e: 0.377 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.056 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 250 pieces\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: KP66158\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696320020786,"sku":"KP66158","price":49.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b9ba3e10d883249098f4bf0efad29e63.jpg?v=1788341458","url":"https:\/\/voomisupply.com\/products\/value-collection-kp66158-split-lock-washer-12-screw-250pk","provider":"Voomi Supply","version":"1.0","type":"link"}
