Split lock washers are installed under fastener heads or nuts to provide spring tension that resists loosening caused by vibration and dynamic loads. This washer measures 0.564 to 0.574 inches inside diameter, 0.965 inches maximum outside diameter, and 0.141 inches thick. The zinc yellow dichromate coating provides corrosion resistance in moderate-exposure environments. Sold in a package of 25, this part is suitable for HVAC equipment assembly, electrical panel mounting, plumbing fixture installation, and general mechanical fastening applications handled by trade professionals.\u003c\/p\u003e\u003cp\u003eThis split lock washer is used wherever a 9\/16 inch fastener requires vibration-resistant retention. Typical applications include equipment mounting, structural brackets, junction box covers, and mechanical assemblies in residential and light commercial settings. The alloy steel construction handles moderate clamping loads without deforming under torque. The zinc yellow dichromate finish suits indoor and sheltered outdoor installations where mild corrosion protection is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI 4037 alloy steel construction for reliable spring tension and load resistance\u003c\/li\u003e\n\u003cli\u003eZinc yellow dichromate finish for moderate corrosion protection\u003c\/li\u003e\n\u003cli\u003eInside diameter range of 0.564 to 0.574 inches for consistent fit on 9\/16 inch fasteners\u003c\/li\u003e\n\u003cli\u003e0.141 inch thickness delivers proper split-lock spring action under torque\u003c\/li\u003e\n\u003cli\u003e0.965 inch maximum outside diameter provides adequate bearing surface\u003c\/li\u003e\n\u003cli\u003eSold in a package of 25 for multi-fastener jobs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 9\/16 inch screw and bolt fasteners in standard inch-measurement assemblies across HVAC, plumbing, electrical, and general mechanical applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by HVAC technicians, electricians, plumbers, and general mechanics using standard hand tools or impact drivers. Always de-energize electrical equipment and shut off relevant utilities before disassembling fastened assemblies. Place the split lock washer between the fastener head or nut and the mating surface with the split gap oriented consistently. Do not reuse lock washers that have been fully compressed flat, as they will no longer provide adequate spring tension.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: 9\/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\u003c\/strong\u003e: Zinc Yellow Dichromate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Inside Diameter\u003c\/strong\u003e: 0.564 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Inside Diameter\u003c\/strong\u003e: 0.574 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Outside Diameter\u003c\/strong\u003e: 0.965 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.141 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: 25\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: 39730\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721731473714,"sku":"39730","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ef2e7d595e59756605efdb2b53110f86.jpg?v=1788580022","url":"https:\/\/voomisupply.com\/products\/value-collection-39730-split-lock-washer-9-16-in-pack-25","provider":"Voomi Supply","version":"1.0","type":"link"}
