The insert features a 5\/8-18 internal thread and a 7\/8-14 external thread, with an overall length of 0.87 inches. Constructed from 303 stainless steel with a passivated finish, it resists corrosion and is suited for demanding environments. Machinists, toolmakers, and maintenance professionals install this type of insert to restore or upgrade threaded bores in metal components where thread integrity is critical.\u003c\/p\u003e\u003cp\u003eThis keylocking insert is used in applications requiring a mechanically locked thread that will not rotate or back out under vibration, shock, or high torque loads. Typical install scenarios include production tooling, machine frames, hydraulic manifolds, and heavy industrial equipment where standard threaded holes have failed or where a stronger thread form is specified from the outset. The passivated stainless steel construction makes it appropriate for use in corrosive or washdown environments common in food processing, marine, and chemical processing applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/8-18 internal thread for standard fastener engagement\u003c\/li\u003e\n\u003cli\u003e7\/8-14 external thread for installation into the parent bore\u003c\/li\u003e\n\u003cli\u003eHeavy-duty keylocking design mechanically locks the insert against rotation and axial pullout\u003c\/li\u003e\n\u003cli\u003e303 stainless steel construction with passivated finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003e0.87 inches overall length suits typical bore depth requirements in metal workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or upgrade keylocking thread insert for industrial and tooling applications requiring a 5\/8-18 internal thread and a 7\/8-14 external installation thread in metal parent materials.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a machinist or maintenance technician using a dedicated keylocking insert installation tool. The parent bore must be drilled and tapped to the correct 7\/8-14 thread specification before the insert is driven in. Keys are then driven into the locking slots to anchor the insert permanently against the bore wall. Always follow the insert manufacturer's installation procedure and ensure the parent material is suitable for the external thread size before boring.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Thread Size\u003c\/strong\u003e: 5\/8-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal Thread Size\u003c\/strong\u003e: 7\/8-14\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.87 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Type\u003c\/strong\u003e: Heavy-Duty Keylocking\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 303\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Passivated\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: 215-069508\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JERGENS","offers":[{"title":"Default Title","offer_id":51981023248690,"sku":"215-069508","price":78.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f3cc0acfc48bc1ae8c988addb4503f6a.jpg?v=1789982055","url":"https:\/\/voomisupply.com\/products\/jergens-215-069508-keylocking-thread-insert-5-8-18-x-7-8-14","provider":"Voomi Supply","version":"1.0","type":"link"}
