Heli-coil A1185-06CN276 Free Running Insert 6-32 0.276in

Product Description

The HELI-COIL A1185-06CN276 is a free running wire thread insert designed to create strong, wear-resistant internal threads in parent materials that cannot support durable fastener engagement on their own. Machined from 304 stainless steel with a bright, uncoated finish, this tanged insert accepts a 6-32 UNC thread and measures 0.276 inches overall length, placing it in the 2D length-to-diameter ratio class. It is installed by maintenance technicians, assembly workers, and field service professionals in applications where thread repair or thread reinforcement is required.

Free running inserts of this type are used across industrial, aerospace-adjacent, and commercial maintenance applications wherever a 6-32 UNC fastener must seat into aluminum, magnesium, cast iron, plastic, or other materials prone to thread stripping. The 2D insert length is a common choice for moderate-load thread reinforcement where parent material depth is limited. Each package contains one insert, with a minimum order quantity of 10 units, making this suited for stocking in service kits or repair trays.

Key Features

• 6-32 UNC thread size for standard coarse-pitch fastener compatibility
• 0.276 inch overall length at 2D length-to-diameter ratio
• 304 stainless steel construction resists corrosion and galvanic degradation
• Tanged design for use with standard HELI-COIL installation tooling
• Bright, uncoated finish - no coating thickness to account for in tight-tolerance bores
• 6 to 6-7/8 free coils provide consistent spring tension during installation

Compatibility

Designed as an OEM-style free running thread insert for use in any parent material tapped to the HELI-COIL 6-32 UNC insert-ready tap specification. Requires the corresponding HELI-COIL tang break-off tool after installation.

Installation Notes

Installation requires a properly sized HELI-COIL tap to prepare the parent bore, followed by the correct mandrel-style installation tool matched to the 6-32 insert. Always clean and deburr the tapped hole before driving the insert. After the insert is seated flush or slightly below the surface, use a tang break-off tool to remove the drive tang. Do not attempt to install with improvised tooling, as coil distortion will compromise thread integrity.
