The insert accepts a 5\/16-18 internal thread and is driven into a 7\/16-14 external thread preparation, both in UNC form. At 0.43 inches overall length, the insert is suited for applications where wall thickness is limited. It is manufactured from C1215 carbon steel with a zinc phosphate coating for corrosion resistance. Machinists, maintenance technicians, and assembly professionals install these inserts to create reliable threaded connections in metallic components.\u003c\/p\u003e\u003cp\u003eThis insert is used in industrial and manufacturing environments where a secure, permanent threaded hole is required in a parent material. The thin wall design allows installation in tighter material cross-sections compared to standard keylocking inserts. Typical applications include machinery frames, fixtures, tooling plates, and structural assemblies where thread pull-out resistance and vibration resistance are critical. The keylocking design uses keys that are driven into the host material to lock the insert against rotation and axial movement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThin wall keylocking design for use in limited-wall-thickness applications\u003c\/li\u003e\n\u003cli\u003e5\/16-18 internal thread with Class 2B fit for standard UNC fastener engagement\u003c\/li\u003e\n\u003cli\u003e7\/16-14 external thread with Class 2A fit for installation into prepared host bore\u003c\/li\u003e\n\u003cli\u003eC1215 carbon steel construction for strength and machinability\u003c\/li\u003e\n\u003cli\u003eZinc phosphate coating provides corrosion resistance\u003c\/li\u003e\n\u003cli\u003eMeets NAS 1394 standard for keylocking insert performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation keylocking thread insert for metallic host materials requiring a 7\/16-14 external thread preparation and a 5\/16-18 internal thread output per UNC standards and NAS 1394.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or maintenance technicians using a keylocking insert installation tool to drive the locking keys into the host material after threading the insert into the prepared bore. The host material bore must be properly sized and tapped to the 7\/16-14 external thread specification before insert installation. Ensure the host assembly is secured and de-energized or depressurized as appropriate before modifying threaded connections. Do not reuse an insert once the locking keys have been driven, as the locking engagement cannot be reset.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Thread Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal Thread Size\u003c\/strong\u003e: 7\/16-14\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Thread Class of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal Thread Class of Fit\u003c\/strong\u003e: 2A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.43 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Type\u003c\/strong\u003e: Thin Wall Keylocking\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C1215\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Zinc Phosphate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: NAS 1394\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: JERGENS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 215-065923\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JERGENS","offers":[{"title":"Default Title","offer_id":52068049879346,"sku":"215-065923","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4b009ee09f780a2965bab1cbda68d8a0.jpg?v=1790046778","url":"https:\/\/voomisupply.com\/products\/jergens-215-065923-keylocking-thread-insert-5-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
