It features an M3 x 0.5 internal thread and an M6 x 1 external thread, manufactured from C12L14 carbon steel to a metric coarse thread standard. At 6.5 mm overall length, the insert installs into a pre-tapped hole and locks mechanically to the parent material wall, resisting rotation and pullout. Tensile strength is rated at 1,299 pounds. Machinists, maintenance technicians, and assembly professionals use this insert to repair stripped threads or establish strong metric thread engagement in production and field applications.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for applications where a reliable M3 thread is required in a larger M6-tapped bore. Typical uses include thread repair in carbon steel, cast iron, or similar ferrous parent materials across industrial, mechanical, and equipment assembly contexts. The self-lock wall design provides positive retention without adhesives or external locking features, making it appropriate for both production line and field repair work. Standard tap tooling is required for installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM3 x 0.5 internal thread with 6H class of fit for precise engagement\u003c\/li\u003e\n  \u003cli\u003eM6 x 1 external thread with 6G class of fit for accurate installation bore sizing\u003c\/li\u003e\n  \u003cli\u003eSelf-lock wall design resists rotation and pullout without adhesives\u003c\/li\u003e\n  \u003cli\u003e1,299 pound tensile strength for high-load thread engagement\u003c\/li\u003e\n  \u003cli\u003eC12L14 carbon steel construction with smooth rolled finish\u003c\/li\u003e\n  \u003cli\u003eMetric coarse thread standard compatible with standard tap tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style thread repair and installation insert for ferrous parent materials requiring an M6 x 1 external installation bore and an M3 x 0.5 internal thread.

Ensure the parent material bore is clean and deburred before installation. Minimum order quantity is 10 units. Follow manufacturer installation tooling recommendations to avoid cross-threading or insert deformation during seating.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Thread Size\u003c\/strong\u003e: M3 x 0.5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExternal Thread Size\u003c\/strong\u003e: M6 x 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 6.5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Thread Class of Fit\u003c\/strong\u003e: 6H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExternal Thread Class of Fit\u003c\/strong\u003e: 6G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTensile Strength\u003c\/strong\u003e: 1,299 pounds\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\u003eThread-Locking Insert Type\u003c\/strong\u003e: Self-Lock Wall\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: 0.0016 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: 450-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"E-Z LOK","offers":[{"title":"Default Title","offer_id":67907747807538,"sku":"450-3","price":31.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0ccb9b925b7d2aa5867f38e5832c3f0d.jpg?v=1791181270","url":"https:\/\/voomisupply.com\/products\/e-z-lok-450-3-thread-locking-insert-m3-x-0-5-metric","provider":"Voomi Supply","version":"1.0","type":"link"}
