Built from Grade 304 stainless steel with a bright finish, this tanged insert measures 0.164 inches in overall length with a 1D length-to-diameter ratio and an 8-32 UNC thread size. The coiled design provides a locking function through 3-1\/2 free coils, resisting loosening under dynamic loads. Licensed trades and maintenance technicians install these inserts in metal fabrication, aerospace, marine, and general industrial applications where thread integrity is critical.\u003c\/p\u003e\u003cp\u003eThis insert is suited for use in applications where stainless steel corrosion resistance is required alongside positive thread locking. The 8-32 UNC thread profile fits standard coarse-pitch fastener configurations. With a minimum outside diameter of 0.205 inches and a maximum outside diameter of 0.220 inches, it installs into a properly tapped hole prepared with the correct HELI-COIL installation tap. Typical use cases include equipment assemblies, enclosures, and components subject to repeated fastener removal or vibration exposure. This product is sold as a single insert (Pkg Qty 1) with a minimum order quantity of 100 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 304 stainless steel construction provides corrosion resistance in wet or chemically exposed environments\u003c\/li\u003e\n\u003cli\u003eScrew-locking design with 3-1\/2 free coils delivers a maximum locking torque of 9 in\/lb\u003c\/li\u003e\n\u003cli\u003eMinimum break-away torque of 1.50 in\/lb ensures the insert remains in place under service loads\u003c\/li\u003e\n\u003cli\u003e8-32 UNC tanged configuration for positive installation and controlled seating depth\u003c\/li\u003e\n\u003cli\u003eBright finish; overall insert length of 0.164 inches at a 1D length-to-diameter ratio\u003c\/li\u003e\n\u003cli\u003eOutside diameter range of 0.205 to 0.220 inches for a secure press fit in the prepared bore\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style screw-locking threaded insert for 8-32 UNC threaded hole applications requiring a 1D insert length in parent materials prepared with the appropriate HELI-COIL installation tap and drill size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires the correct HELI-COIL tap to prepare the parent material bore before the insert is driven using a compatible installation tool. Power down or de-energize any equipment before performing thread repair or insert installation. After seating the insert to the correct depth, remove the installation tang using a tang break-off tool. Follow applicable fastener and assembly standards for the end-use application, and verify locking torque requirements are met after installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Insert Length\u003c\/strong\u003e: 0.164 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength-to-Diameter Ratio\u003c\/strong\u003e: 1D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Outside Diameter\u003c\/strong\u003e: 0.205 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Outside Diameter\u003c\/strong\u003e: 0.220 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Free Coils\u003c\/strong\u003e: 3-1\/2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Locking Torque\u003c\/strong\u003e: 9 in\/lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Break-Away Torque\u003c\/strong\u003e: 1.50 in\/lb\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: 304\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTang\u003c\/strong\u003e: Tanged\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.001 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HELI-COIL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: AT3585-2C164\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":51974044418354,"sku":"AT3585-2C164","price":120.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/777d0c44c3fa0a3c21c4dd4bd1dfcc1d.jpg?v=1789975592","url":"https:\/\/voomisupply.com\/products\/heli-coil-at3585-2c164-screw-locking-insert-8-32-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
