Split lock washers create a spring-tension bite against fastener and mating surface, resisting loosening caused by vibration or thermal cycling. The inside diameter ranges from 0.44 to 0.45 inches with a maximum outside diameter of 0.776 inches and a thickness of 0.109 inches. This washer is installed by electricians, plumbers, HVAC technicians, and general mechanical tradespeople wherever vibration-resistant fastening is required in light to medium-duty assemblies.\u003c\/p\u003e\n\u003cp\u003eThis split lock washer is suited for residential and commercial mechanical, electrical, and plumbing applications where standard inch-series fasteners are used. It is appropriate for equipment mounting, panel attachment, pipe hanger hardware, conduit support, and similar installations that call for a 7\/16 inch screw with a lock washer. The zinc yellow dichromate finish provides a baseline level of corrosion resistance for indoor and protected outdoor environments. Sold in a package of 50 pieces, making it practical for service vehicles and job-site inventory.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAISI 4037 alloy steel construction for reliable spring tension and hardness\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish provides corrosion resistance in typical service environments\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 0.44 to 0.45 inches fits standard 7\/16 inch fasteners\u003c\/li\u003e\n  \u003cli\u003eMaximum outside diameter of 0.776 inches and thickness of 0.109 inches conform to standard split lock washer geometry\u003c\/li\u003e\n  \u003cli\u003eInch measurement system — compatible with standard SAE fastener sets\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 50 pieces supports efficient job-site stocking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 7\/16 inch screw fasteners in inch-series mechanical assemblies across HVAC, plumbing, electrical, and general equipment installation applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall split lock washers between the fastener head or nut and the mating surface with the split ends oriented to bite into both surfaces as the fastener is tightened. Ensure the mating surface is clean and free of debris before assembly to allow proper seating. Do not reuse split lock washers that have been fully flattened, as they will no longer provide effective locking tension. Follow applicable mechanical codes and equipment manufacturer torque specifications when securing assemblies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: 7\/16 inches\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: 0.44 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Inside Diameter\u003c\/strong\u003e: 0.45 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Outside Diameter\u003c\/strong\u003e: 0.776 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.109 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: 50 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: 39728\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721366765874,"sku":"39728","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/95cfe72cbe79576167bfc47c44a4cf8b.jpg?v=1788576817","url":"https:\/\/voomisupply.com\/products\/value-collection-39728-split-lock-washer-7-16-in-alloy-steel-50pk","provider":"Voomi Supply","version":"1.0","type":"link"}
