Heli-coil A1185-06GN207 6-32 Unc Titanium Free Running Insert

Product Description

The HELI-COIL A1185-06GN207 is a free running helical wire thread insert designed to create strong, wear-resistant internal threads in tapped holes. This tanged insert measures 0.207 inches in overall length with a 6-32 UNC thread size and a 1-1/2D length-to-diameter ratio, placing it in the standard category for thread repair and thread reinforcement applications. Manufactured from titanium with a bright, uncoated finish, it delivers a high strength-to-weight ratio suitable for aerospace, precision mechanical, and industrial assembly work. Installation requires a correctly sized pre-tap and the appropriate HELI-COIL installation tool for the 6-32 thread series.

This insert is used wherever a 6-32 UNC internal thread must be installed, repaired, or reinforced in a parent material that may be softer or more prone to thread damage than the fastener itself. Typical applications include light-gauge aluminum housings, electronic enclosures, instrument panels, and precision machined components where thread stripping is a concern or where a titanium insert is specified for weight savings or corrosion resistance. The tanged design means a notch-breaking tool is required to remove the driving tang after installation.

Key Features

• 6-32 UNC thread size for compatibility with standard inch-series fasteners in that class
• Titanium construction provides high strength with minimal added weight
• Bright, uncoated finish suitable for applications where coatings are not specified
• Tanged design aids driving during installation; tang is broken off flush after seating
• 1-1/2D length-to-diameter ratio delivers reliable thread engagement depth
• 4-3/4 free coils for consistent locking and load distribution along the thread helix

Compatibility

Designed as an OEM-style free running insert for use in any 6-32 UNC tapped hole prepared with the corresponding HELI-COIL STI tap for the 6-32 thread series.

Installation Notes

Installation is performed by a machinist or assembly technician using the correct STI tap to prepare the parent hole, followed by the appropriate HELI-COIL driving tool sized for the 6-32 series. Power down and de-energize any assembly before reworking threaded holes in electrical or electronic enclosures. After the insert is fully seated, use a tang break-off tool to remove the driving tang; never leave the tang in place in a load-bearing hole. Follow the insert manufacturer's installation depth guidelines to ensure full thread engagement.
