The insert features an M12 x 1.75 internal thread and a 3\/4-10 external thread, allowing it to be driven into a tapped host material while presenting a metric internal thread for fastener engagement. Constructed from grade 303 stainless steel with a bright finish, it measures 21\/32 inches in overall length and weighs approximately 0.04 pounds. Licensed tradespeople and maintenance technicians working with metric fastener applications use this insert when thread repair or thread conversion is required.\u003c\/p\u003e\u003cp\u003eThis insert is suited for applications where a metric coarse or metric fine internal thread must be anchored in a component tapped with a standard 3\/4-10 thread. Typical use cases include industrial equipment repair, structural assemblies, and precision thread restoration in metal or high-density substrates. The standard wall design is appropriate for applications with adequate host material wall thickness to accommodate the external thread engagement. Installation requires a standard tap sized for the 3\/4-10 external thread profile.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM12 x 1.75 internal thread with 2B class of fit for reliable metric fastener engagement\u003c\/li\u003e\n\u003cli\u003e3\/4-10 external thread with 2A class of fit for secure installation in host material\u003c\/li\u003e\n\u003cli\u003eGrade 303 stainless steel construction resists corrosion and wear\u003c\/li\u003e\n\u003cli\u003eBright finish on all surfaces\u003c\/li\u003e\n\u003cli\u003eStandard wall design suits applications with sufficient surrounding material thickness\u003c\/li\u003e\n\u003cli\u003eCompatible with both metric coarse and metric fine thread standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style thread locking insert for applications requiring an M12 x 1.75 internal thread installed via a 3\/4-10 externally threaded insert in standard wall configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a machinist or maintenance technician using a standard tap sized for the 3\/4-10 external thread. The host material must be tapped to the correct depth before driving the insert to avoid cross-threading or damage to the internal thread. De-energize or lock out any equipment before performing thread repair work on components in service. Follow applicable facility maintenance and safety procedures when working with threaded fastener systems.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Thread Size\u003c\/strong\u003e: M12 x 1.75\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: Metric Coarse, Metric Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 21\/32 inches (0.6560 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWall Type\u003c\/strong\u003e: Standard Wall\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 303\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\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\u003eFor Tap Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 653-12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"E-Z LOK","offers":[{"title":"Default Title","offer_id":67906659189042,"sku":"653-12","price":66.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e06270279fd15c94c4a6a1ec82725ce0.jpg?v=1791170204","url":"https:\/\/voomisupply.com\/products\/e-z-lok-653-12-thread-locking-insert-m12-x-1-75-stainless","provider":"Voomi Supply","version":"1.0","type":"link"}
