Manufactured from Grade 304 stainless steel with a dry film lubricant finish, this insert accepts a 10-24 UNC mating thread and measures 0.285 inches in overall length at a 1-1\/2D length-to-diameter ratio. The locking feature is built into the coil geometry, providing a controlled prevailing-torque fit that resists loosening under dynamic loads. Installation is performed by machinists, maintenance technicians, and assembly professionals working on metal fabrication, equipment repair, and precision mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for applications where thread stripping, corrosion exposure, or repeated fastener cycling demands a reinforced internal thread. The tangless design eliminates the need for tang removal after installation, reducing assembly steps and preventing loose tang fragments inside assemblies. Common use cases include aerospace component repair, industrial equipment maintenance, and precision instrument manufacturing where stainless steel corrosion resistance and controlled locking torque are required specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTangless design eliminates post-installation tang removal and prevents debris contamination\u003c\/li\u003e\n  \u003cli\u003eGrade 304 stainless steel construction provides corrosion resistance in demanding service environments\u003c\/li\u003e\n  \u003cli\u003eDry film lubricant finish supports controlled installation torque and consistent locking performance\u003c\/li\u003e\n  \u003cli\u003eMaximum locking torque of 13 inch-pounds with a minimum breakaway torque of 2.00 inch-pounds\u003c\/li\u003e\n  \u003cli\u003e5 free coils provide even load distribution across the threaded engagement zone\u003c\/li\u003e\n  \u003cli\u003eOutside diameter range of 0.244 to 0.259 inches for accurate fit in standard Heli-Coil tapped holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a screw-locking wire thread insert for use in standard 10-24 UNC tapped holes prepared to Heli-Coil tangless insert specifications.

The parent material hole must be tapped using the specified Heli-Coil tap to achieve the correct minor diameter before insert installation. Ensure all chips and debris are cleared from the tapped hole prior to driving the insert. No tang extraction step is required with tangless inserts, but verify full seating depth before assembling the mating fastener.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10-24 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Insert Length\u003c\/strong\u003e: 0.285 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength to Diameter Ratio\u003c\/strong\u003e: 1-1\/2D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Outside Diameter\u003c\/strong\u003e: 0.244 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Outside Diameter\u003c\/strong\u003e: 0.259 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Free Coils\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Locking Torque\u003c\/strong\u003e: 13 inch-pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Breakaway Torque\u003c\/strong\u003e: 2.00 inch-pounds\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\u003eCoating\/Finish\u003c\/strong\u003e: Dry Film Lubricant\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTang\u003c\/strong\u003e: Tangless\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: HELI-COIL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A3585-3CNW285\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":52083644465458,"sku":"A3585-3CNW285","price":27.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/af73ce0b1c2fadcfd9c1cbb6742d6d49.jpg?v=1790057629","url":"https:\/\/voomisupply.com\/products\/heli-coil-a3585-3cnw285-screw-locking-insert-10-24-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
