Featuring a 5\/8-18 UNF internal thread and a 7\/8-9 external thread, this insert installs into a tapped hole and locks against the parent material wall to prevent rotation and back-out under load. The insert measures 0.687 inches in length and is manufactured from C12L14 carbon steel with a smooth, rolled finish. It is suited for applications where a reliable threaded repair or thread reinforcement is required in steel or similarly hard parent materials. Machinists, maintenance technicians, and mechanical assemblers working in industrial or trade settings are the primary installers.\u003c\/p\u003e\u003cp\u003eThe 329-10F is used in applications requiring a durable UNF thread insert in metal components subject to vibration, repeated fastener cycling, or torque loading. The self-lock wall design mechanically locks the insert to the parent material, eliminating the need for adhesive retention methods. This insert is appropriate for use in production machining, MRO repair work, and field repair of stripped or damaged threads in carbon steel assemblies. A standard tap compatible with the 7\/8-9 external thread is required for proper installation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/8-18 UNF internal thread with a 2B class of fit for standard fastener engagement\u003c\/li\u003e\n\u003cli\u003e7\/8-9 external thread with a 2A class of fit sized for a standard tap installation\u003c\/li\u003e\n\u003cli\u003eSelf-lock wall design mechanically locks insert to parent material without adhesive\u003c\/li\u003e\n\u003cli\u003eC12L14 carbon steel construction for strength in metal-to-metal applications\u003c\/li\u003e\n\u003cli\u003eSmooth, rolled finish on external thread for consistent installation torque\u003c\/li\u003e\n\u003cli\u003eInsert length of 0.687 inches provides full thread engagement depth\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for installation into carbon steel and comparable parent materials tapped to accept a 7\/8-9 external thread using a standard tap.

Ensure the parent material is securely fixtured before tapping to maintain thread alignment. The insert should be driven to the specified seating depth using an appropriate installation tool to fully engage the self-locking wall feature. De-energize or lock out any powered equipment before performing threaded insert repairs on assemblies in service.\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\/8-9\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: 0.687 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\u003eFor Tap Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0381 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: 329-10F\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"E-Z LOK","offers":[{"title":"Default Title","offer_id":67906649686322,"sku":"329-10F","price":25.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ae1f30f3535b7265acf4448dad14a11d.jpg?v=1791170111","url":"https:\/\/voomisupply.com\/products\/e-z-lok-329-10f-thread-locking-insert-5-8-18-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
