The split helical design bites into the bearing surface and fastener head when the assembly is torqued, resisting loosening caused by vibration and dynamic loads. A zinc yellow dichromate finish provides corrosion resistance suitable for general industrial and mechanical applications. This washer ships in a box quantity of 100 pieces, making it practical for production assembly, maintenance shops, and field service kits. Typical installers include millwrights, pipefitters, electricians, and general mechanical contractors working with high-strength fastener assemblies.\u003c\/p\u003e\u003cp\u003eThis split lock washer is suited for use anywhere a 9\/16 inch fastener requires positive locking under vibration or cyclic loading. Common applications include structural steel connections, mechanical equipment mounting, HVAC equipment bases, electrical enclosure hardware, and general industrial maintenance. The Grade 8 material rating indicates high tensile strength suitable for demanding mechanical joints. The zinc yellow dichromate finish is compatible with indoor and moderate-exposure outdoor environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 8 steel construction for high-strength fastener assemblies\u003c\/li\u003e\n\u003cli\u003eSplit helical profile resists fastener loosening under vibration\u003c\/li\u003e\n\u003cli\u003eZinc yellow dichromate finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eInside diameter range of 0.564 to 0.574 inches fits standard 9\/16 inch screws and bolts\u003c\/li\u003e\n\u003cli\u003eMaximum outside diameter of 0.965 inches for compact bearing surface\u003c\/li\u003e\n\u003cli\u003eBox quantity of 100 pieces for shop stock or production use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 9\/16 inch screws and bolts in standard inch-measurement fastener assemblies requiring a Grade 8 split lock washer.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall with the split gap oriented so the washer can compress fully as the fastener is torqued to specification. Always degrease mating surfaces before assembly to ensure consistent clamp load. Follow applicable mechanical or structural codes for proper fastener torque values when used in load-bearing connections. Inspect washers for cracks or deformation before reuse — split lock washers are typically single-use components in critical joints.\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: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 8\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: 0.564 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: 100 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161801\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: LWIA0561USA-100BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691931107634,"sku":"LWIA0561USA-100BX","price":3092.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/46cb78fccd3056ab818dab664c8c8b69.jpg?v=1788291158","url":"https:\/\/voomisupply.com\/products\/value-collection-lwia0561usa-100bx-grade-8-split-lock-washer","provider":"Voomi Supply","version":"1.0","type":"link"}
