The insert features a 7\/16-20 internal thread and a 5\/8-11 external thread, both to UNF standards, with a total length of 0.620 inches. Manufactured from C1215 carbon steel with a zinc phosphate coating, it is suited for applications where pull-out resistance and vibration resistance are critical. Licensed HVAC, industrial maintenance, and mechanical assembly professionals install this type of insert using standard keylocking installation tooling.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in metal fabrication, industrial equipment repair, and mechanical assembly applications where a damaged or soft parent-material thread must be reinforced or replaced. The heavy-duty keylocking design mechanically locks the insert in place, preventing rotation under load or vibration. The compact 0.620-inch overall length makes it suitable for use in tight or shallow-bore situations where a full-length insert would not fit. It is a direct-install solution for restoring or upgrading threaded connections in carbon steel, aluminum, and cast housings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/16-20 internal thread (Class 2B fit) accepts standard UNF fasteners\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 external thread (Class 2A fit) for secure engagement in the parent material\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty keylocking design resists rotation and pullout under vibration\u003c\/li\u003e\n  \u003cli\u003eC1215 carbon steel construction with zinc phosphate coating for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eCompact 0.620-inch overall length suits shallow-bore and space-constrained installations\u003c\/li\u003e\n  \u003cli\u003eUNF thread standard throughout for compatibility with standard inch-series tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or upgrade insert for industrial and mechanical assemblies requiring a heavy-duty UNF keylocking threaded insert with 7\/16-20 internal and 5\/8-11 external thread specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of keylocking thread inserts requires a properly tapped parent-material bore sized to the 5\/8-11 external thread specification before the insert is driven in. Power down or de-energize any associated equipment before beginning thread repair work. Use the correct keylocking installation driver to seat the insert and stake the locking keys without damaging the parent material. Follow applicable machine safety and maintenance codes for the equipment being serviced.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Thread Size\u003c\/strong\u003e: 7\/16-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExternal Thread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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: 0.620 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: 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\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\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: JERGENS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 215-066105\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JERGENS","offers":[{"title":"Default Title","offer_id":52043415683378,"sku":"215-066105","price":15.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ef9695e4afab2c480ffcd8c97841934a.jpg?v=1790029047","url":"https:\/\/voomisupply.com\/products\/jergens-215-066105-keylocking-thread-insert-7-16-20","provider":"Voomi Supply","version":"1.0","type":"link"}
