Manufactured from Grade 304 stainless steel with a primer-free finish, this insert accepts 8-32 UNC fasteners and installs at a 1D length-to-diameter ratio, with an overall length of 0.164 inches. The coil design provides a locking function with a maximum locking torque of 9 inch-pounds and a minimum breakaway torque of 1.50 inch-pounds. Machinists, maintenance technicians, and assembly professionals install this type of insert in metalworking, aerospace, and industrial maintenance applications where thread integrity is critical.\u003c\/p\u003e\u003cp\u003eThis insert is suited for use in ferrous and non-ferrous base materials where a durable, corrosion-resistant 8-32 UNC internal thread is required. The tangless design eliminates the need to remove a tang after installation, reducing installation time and preventing loose tang debris inside assembled components. It is commonly used in precision assemblies, housings, and enclosures where contamination from tang removal is a concern. The primer-free finish is compatible with clean-room and close-tolerance installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTangless design eliminates post-installation tang removal and reduces debris risk\u003c\/li\u003e\n\u003cli\u003eGrade 304 stainless steel construction provides corrosion resistance in demanding environments\u003c\/li\u003e\n\u003cli\u003eMaximum locking torque of 9 inch-pounds helps resist fastener back-out under vibration\u003c\/li\u003e\n\u003cli\u003eMinimum breakaway torque of 1.50 inch-pounds ensures controlled re-entry access\u003c\/li\u003e\n\u003cli\u003ePrimer-free finish compatible with clean and close-tolerance assemblies\u003c\/li\u003e\n\u003cli\u003e3-1\/2 free coils with outside diameter range of 0.205 to 0.220 inches for secure seating in the host bore\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or original installation insert for applications requiring an 8-32 UNC internal thread with a 1D length-to-diameter ratio in a host material prepared to accept a standard helical insert bore diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachinist or maintenance technician installation is typical; the host material must be drilled and tapped to the correct insert tap size for 8-32 UNC before the insert is driven in using a compatible tangless insert installation tool. Power down and de-energize any equipment before performing thread repair or insert installation on live assemblies. Do not use a standard tang-type installation tool with tangless inserts, as the drive geometry is not interchangeable. Follow applicable facility safety and torque verification procedures 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\u003eThread Standard\u003c\/strong\u003e: 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 inch-pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Breakaway Torque\u003c\/strong\u003e: 1.50 inch-pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTang\u003c\/strong\u003e: Tangless\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: Primer Free\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: HELI-COIL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A3585-2CNPF164\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":52034526314802,"sku":"A3585-2CNPF164","price":31.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/89e34a30499c67b6269a2214ae27ed4f.jpg?v=1790022388","url":"https:\/\/voomisupply.com\/products\/heli-coil-a3585-2cnpf164-screw-locking-insert-8-32-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
