Machined from C12L14 carbon steel with a smooth, rolled finish, this insert features a 7\/16-14 UNC internal thread and a 5\/8-11 UNC external thread. The overall length is 21\/32 inches (0.656 inches decimal). With a tensile strength of 17,201 pounds, the 329-7 is built for demanding mechanical assemblies where thread integrity is critical. Installation is performed using a standard tap, making it a straightforward add for machinists, maintenance technicians, and MRO professionals.\u003c\/p\u003e\u003cp\u003eThis insert is suited for applications where a parent material requires reinforced threading or where stripped threads need to be restored to full load-bearing capacity. Common install scenarios include industrial machinery, structural assemblies, and equipment requiring reliable UNC thread engagement. The self-lock wall design provides resistance to loosening under vibration and dynamic loading without requiring thread-locking compounds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/16-14 UNC internal thread with 2B class of fit for standard fastener compatibility\u003c\/li\u003e\n\u003cli\u003e5\/8-11 UNC external thread with 2A class of fit for secure parent-material engagement\u003c\/li\u003e\n\u003cli\u003eSelf-lock wall design resists loosening under vibration without adhesives\u003c\/li\u003e\n\u003cli\u003eTensile strength rated at 17,201 pounds for high-load applications\u003c\/li\u003e\n\u003cli\u003eC12L14 carbon steel construction with smooth, rolled finish\u003c\/li\u003e\n\u003cli\u003eInstalls using a standard tap  -  no specialty tooling required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style thread locking insert for applications requiring a 5\/8-11 UNC external thread drilled and tapped hole with a 7\/16-14 UNC internal thread requirement.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a machinist or qualified maintenance technician. The parent material must be drilled and tapped to the correct 5\/8-11 UNC specification before the insert is driven in. Ensure the work piece is secured and de-energized or depressurized as appropriate for the assembly before beginning thread repair or insert installation. Follow the equipment manufacturer's torque specifications for the fastener engaging the internal thread after insert installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Thread Size\u003c\/strong\u003e: 7\/16-14\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: 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: 21\/32 inches (0.656 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread-Locking Insert Type\u003c\/strong\u003e: Self-Lock Wall\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: C12L14\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Smooth, Rolled\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTensile Strength\u003c\/strong\u003e: 17,201 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor Tap Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0201 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: E-Z LOK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 329-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"E-Z LOK","offers":[{"title":"Default Title","offer_id":67912821768498,"sku":"329-7","price":22.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b6bc4f251926bdadc239a9a6f305293_208de0b8-0122-494c-9b46-ccb9fb2bec23.jpg?v=1791239995","url":"https:\/\/voomisupply.com\/products\/e-z-lok-329-7-thread-locking-insert-7-16-14-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
