It features a 1\/2-13 UNC internal thread and a 3\/4-10 UNC external thread, with an overall length of 21\/32 inches (0.656 inches). Manufactured from C12L14 carbon steel with a smooth, rolled finish, this insert delivers a tensile strength of 23,290 pounds. It is installed using a standard tap and is suited for applications requiring a reliable thread repair or thread reinforcement solution in metal assemblies.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in industrial, mechanical, and maintenance applications where a stronger internal thread is needed than the base material can provide on its own. The self-lock wall design resists rotation and loosening under vibration and dynamic load. Fabricators, maintenance mechanics, and field service technicians working with carbon steel assemblies are the primary installers. The 3\/4-10 external thread drives into a tapped hole in the host material, leaving the 1\/2-13 internal thread exposed for fastener engagement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC internal thread with Class 2B fit for standard fastener compatibility\u003c\/li\u003e\n  \u003cli\u003e3\/4-10 UNC external thread with Class 2A fit for installation into host material\u003c\/li\u003e\n  \u003cli\u003eSelf-lock wall design resists loosening under vibration and cyclic loading\u003c\/li\u003e\n  \u003cli\u003eC12L14 carbon steel construction with smooth rolled finish\u003c\/li\u003e\n  \u003cli\u003eTensile strength rated at 23,290 pounds\u003c\/li\u003e\n  \u003cli\u003eCompact 21\/32-inch overall length suits space-constrained assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style threaded insert for use in metal base materials tapped with a standard 3\/4-10 UNC tap.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance mechanics using a standard 3\/4-10 UNC tap to prepare the host material bore. Power down and de-energize any equipment before performing thread repair on in-service components. Use the appropriate E-Z LOK installation tool or a hex key driver to drive the insert flush or slightly below the host material surface. Do not overtighten or cross-thread during installation, as this can compromise the locking wall engagement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Thread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExternal Thread Size\u003c\/strong\u003e: 3\/4-10\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\u003eInsert 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: 23,290 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: 0.033 pounds\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: E-Z LOK\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 329-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"E-Z LOK","offers":[{"title":"Default Title","offer_id":67906558525746,"sku":"329-8","price":24.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7dd40a2d7819c6faddf17824c600df5e_7926736b-c6e6-4395-88a9-5b78f9a58292.jpg?v=1791169164","url":"https:\/\/voomisupply.com\/products\/e-z-lok-329-8-thread-locking-insert-1-2-13-unc-carbon-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
