Heli-coil T1185-06C276S 6-32 Unc Free Running Insert 304 Ss

Product Description

The HELI-COIL T1185-06C276S is a tangless, free running helical wire thread insert designed to create strong, wear-resistant internal threads in parent materials that may be too soft or too thin to hold a standard machine screw thread reliably. Built from 304 stainless steel, this insert measures 0.276 inches in overall length with a 6-32 UNC thread size and a 2D length-to-diameter ratio. Installation requires a dedicated HELI-COIL tap and installation tool. This insert is used by maintenance technicians, aerospace assemblers, and industrial repair professionals who need durable thread repair or thread reinforcement in production and field applications.

This insert is suited for applications where a 6-32 UNC thread must be installed or restored in aluminum, magnesium, cast iron, plastics, or other materials prone to thread stripping or corrosion. The tangless design eliminates the need to remove a drive tang after installation, reducing assembly time and the risk of loose tang fragments inside assemblies. Common application environments include electronics enclosures, instrument panels, light mechanical assemblies, and precision equipment housings. Each package contains 1000 inserts, making this quantity appropriate for production runs and high-volume repair operations.

Key Features

• Tangless design eliminates post-installation tang removal and prevents fragment contamination
• 304 stainless steel construction resists corrosion in demanding service environments
• 6-32 UNC thread size with 0.276 inches overall length and 2D length-to-diameter ratio
• 6-7/8 free coils provide consistent thread engagement across the insert length
• Pack of 1000 inserts supports production and high-volume maintenance use

Compatibility

Designed as an OEM-style threaded insert for use in any parent material requiring a 6-32 UNC internal thread; compatible with standard HELI-COIL installation tooling for tangless free running inserts.

Installation Notes

Installation must be performed by a technician familiar with helical thread insert procedures. The parent material must first be drilled and tapped with the correct HELI-COIL STI tap for 6-32 before the insert is driven. Power must be removed from any electrical assembly before thread repair work begins. Follow the insert manufacturer's installation tool guidelines to ensure proper seating depth and coil engagement.
