The insert features an 8-32 internal thread (UNC\/UNF, Class 2B fit) and an M8 x 1.25 external thread (Class 2A fit) for installation into a standard-tapped M8 receiving hole. Overall length is 0.2953 inches (7.50 mm). Machined from C12L14 carbon steel with a smooth, rolled finish, this insert delivers reliable thread integrity in metal assemblies across industrial and mechanical trade applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for use in metalworking, mechanical assembly, and maintenance applications where a parent material tapped to M8 x 1.25 must accept an 8-32 fastener. It is installed using a standard tap for the external thread and is appropriate for precision assemblies requiring controlled thread fit. Tradespeople and machinists working in manufacturing, equipment repair, and custom fabrication will find this insert useful for thread conversion and thread repair scenarios.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8-32 internal thread with Class 2B fit for standard fastener engagement\u003c\/li\u003e\n\u003cli\u003eM8 x 1.25 external thread with Class 2A fit for installation into standard M8-tapped holes\u003c\/li\u003e\n\u003cli\u003eOverall length of 0.2953 inches (7.50 mm) for compact, space-efficient installation\u003c\/li\u003e\n\u003cli\u003eC12L14 carbon steel construction for durability in metallic base materials\u003c\/li\u003e\n\u003cli\u003eSmooth, rolled finish on external thread for consistent installation torque\u003c\/li\u003e\n\u003cli\u003eCompatible with standard tap type  -  no special tooling required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for installation into parent materials tapped to M8 x 1.25 using a standard tap, accepting 8-32 internal fasteners per UNC\/UNF thread standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a machinist or maintenance technician using a standard M8 x 1.25 tap and an appropriate thread insert driver. Ensure the parent material hole is tapped to the correct depth and tolerance before driving the insert. Power down or de-energize any equipment before performing thread repair or insert installation on assembled machinery. Follow applicable torque specifications for the fastener used in the installed 8-32 internal thread based on the application requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Thread Size\u003c\/strong\u003e: 8-32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal Thread Size\u003c\/strong\u003e: M8 x 1.25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC \/ 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: 0.2953 inches (7.50 mm)\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: 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: 0.0033 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: 550-008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"E-Z LOK","offers":[{"title":"Default Title","offer_id":67910812696882,"sku":"550-008","price":21.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/599d522c9295b4c788430b9cf7ddbd9c.jpg?v=1791200425","url":"https:\/\/voomisupply.com\/products\/e-z-lok-550-008-thread-locking-insert-8-32-internal-m8-x-1-25","provider":"Voomi Supply","version":"1.0","type":"link"}
