Split lock washers are helical spring-type fastener components placed under a nut or screw head to resist loosening caused by vibration and torque relaxation. This washer accepts a number 4 screw with an inside diameter range of 0.114 to 0.12 inches and an outside diameter range of 0.209 to 0.223 inches at a thickness of 0.025 inches. The 18-8 stainless steel construction provides corrosion resistance suited for both indoor and outdoor mechanical assemblies. Electricians, HVAC technicians, plumbers, and general mechanical tradespeople use split lock washers during panel assembly, equipment mounting, and component fastening tasks.\u003c\/p\u003e\n\u003cp\u003eThis washer is appropriate for light-duty fastening applications where a number 4 screw is specified and corrosion resistance is required. Typical use cases include securing electrical enclosure hardware, HVAC equipment panels, plumbing fixture brackets, and small mechanical assemblies. The inch-system sizing makes it compatible with standard SAE number 4 fastener installations in residential and commercial trade work. This part is sold individually but requires a minimum order quantity of 500 units, making it well suited for shop stock, service truck inventory replenishment, or production assembly use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18-8 stainless steel construction resists corrosion in wet and outdoor environments\u003c\/li\u003e\n  \u003cli\u003eSplit helical design creates spring tension that resists fastener back-off under vibration\u003c\/li\u003e\n  \u003cli\u003eInside diameter range of 0.114 to 0.12 inches fits number 4 screws\u003c\/li\u003e\n  \u003cli\u003eOutside diameter range of 0.209 to 0.223 inches provides adequate bearing surface for small-head fasteners\u003c\/li\u003e\n  \u003cli\u003e0.025 inch thickness suits thin-profile fastening applications\u003c\/li\u003e\n  \u003cli\u003eInch system sizing aligns with standard SAE number 4 fastener specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with number 4 inch-system screws and bolts in mechanical, electrical, HVAC, and plumbing assembly applications requiring a split lock washer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePower down all electrical equipment and relieve any system pressure before servicing fastened assemblies. Place the split lock washer between the fastener head or nut and the mating surface, with the split gap positioned away from any conductive contact point on live assemblies. Hand-start the fastener before applying final torque to avoid cocking or deforming the washer. Follow applicable NEC or equipment manufacturer torque guidance for the specific fastener and material being joined.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: Number 4\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Inside Diameter\u003c\/strong\u003e: 0.114 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Inside Diameter\u003c\/strong\u003e: 0.12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Outside Diameter\u003c\/strong\u003e: 0.209 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Outside Diameter\u003c\/strong\u003e: 0.223 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.025 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMilitary Specification\u003c\/strong\u003e: Does Not Meet Military Specifications\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 500\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: R83920111\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723168350514,"sku":"R83920111","price":574.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4685e8064c2e0ff380d482323553e91b.jpg?v=1788601554","url":"https:\/\/voomisupply.com\/products\/value-collection-r83920111-no-4-split-lock-washer-18-8-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
