Manufactured from Grade 5 steel with a bright, uncoated finish, this hex lock nut provides reliable thread locking through its castellated design. It measures 13\/16 inches in height with a 1-1\/8 inch width across flats and follows a right-hand thread direction. The nut conforms to ANSI B18.2.2 standards, making it a recognized, specification-compliant fastener for mechanical and industrial assemblies. Maintenance technicians, millwrights, and field service professionals across HVAC, plumbing, and general mechanical trades install this type of fastener where positive locking is required.\u003c\/p\u003e\n\u003cp\u003eThis castle lock nut is suited for residential and commercial applications where vibration or cyclical loading could cause a standard nut to loosen over time. The castellated profile accepts a cotter pin or safety wire routed through a matching drilled shaft or bolt, creating a positive mechanical lock. Typical installation scenarios include rotating shaft assemblies, linkage hardware, and mechanical equipment requiring tamper-evident or vibration-resistant fastening. The 3\/4-16 fine thread pitch provides a greater number of threads per inch compared to coarse thread variants, improving clamping force and adjustment precision.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCastle lock design accepts cotter pin or safety wire for positive mechanical thread retention\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction provides tensile strength suitable for general industrial and mechanical use\u003c\/li\u003e\n  \u003cli\u003e3\/4-16 unified fine thread for precise adjustment and higher clamping force\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction matches standard bolt and stud configurations\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish for applications where corrosion protection is not a primary requirement\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI B18.2.2 fastener standards for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service fastener for any 3\/4-16 unified fine thread bolt or stud requiring a castle lock nut per ANSI B18.2.2.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or tradesperson using the appropriate open-end or combination wrench sized to 1-1\/8 inches across flats. Always torque to the fastener specification required by the equipment manufacturer, then align the castellation slots with the cotter pin hole before installing the cotter pin or safety wire. Remove all power, pressure, or mechanical energy from the assembly before servicing any fastened joint. Inspect the mating bolt or stud for thread damage before installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNut Type\u003c\/strong\u003e: Castle Lock Nut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 1-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI B18.2.2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: CNFI5075-025BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51788137431346,"sku":"CNFI5075-025BX","price":22.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fab898dbf03a22af87fb5e53f9ccbbbb.jpg?v=1789223499","url":"https:\/\/voomisupply.com\/products\/value-collection-cnfi5075-025bx-castle-lock-nut-3-4-16","provider":"Voomi Supply","version":"1.0","type":"link"}
