Heli-coil 1185-2CN246S Free Running Insert 8-32 Pack 1000

Product Description

The HELI-COIL 1185-2CN246S is a tanged, free running wire thread insert designed to create strong, wear-resistant internal threads in parent materials that cannot reliably hold a thread on their own. Manufactured from 304 stainless steel, this insert accepts an 8-32 UNC thread and measures 0.246 inches in overall length with a 1-1/2D length-to-diameter ratio. It features 6 free coils and a tang for installation tool engagement. Machinists, maintenance technicians, and assembly professionals use these inserts to repair stripped threads or to build in threaded inserts during original fabrication in metals, plastics, and composites.

This insert is suited for production and repair applications across industrial, aerospace, and general manufacturing environments. The 8-32 UNC thread size is common in light-duty fastening applications including electrical panels, instrument housings, and small mechanical assemblies. The 304 stainless steel construction provides corrosion resistance appropriate for environments with moisture exposure or chemical contact. This listing is for a pack of 1000 inserts, making it a practical choice for production-volume use.

Key Features

• 8-32 UNC thread size for wide compatibility in light-duty fastening applications

Compatibility

Designed as an OEM-style thread repair and fabrication insert for parent material tapped to the standard HELI-COIL 8-32 UNC insert tap size.

Installation Notes

Installation requires a parent hole tapped with the correct HELI-COIL insert tap for the 8-32 UNC thread size. A proper installation tool is required to drive the tanged insert to the correct depth; the tang is broken off after installation using a tang break-off tool. Power down or de-energize any assembly before performing thread repair work on live electrical or mechanical components. Follow applicable industry and facility safety procedures when working with cutting tools and rotating equipment.
