Heli-coil A1084-6CN120 Free Running Insert M6 X 1

Product Description

The HELI-COIL A1084-6CN120 is a free running wire thread insert designed to create strong, wear-resistant internal threads in a tapped hole. Made from 304 stainless steel with a bright, uncoated finish, this insert accepts an M6 x 1.00 metric coarse thread and measures 12.0 mm (0.4724 inches) in overall length, giving it a 2D length-to-diameter ratio. The tanged design allows installation with a standard Heli-Coil insertion tool. Installed by machinists, maintenance technicians, and field service professionals, it restores or reinforces threads in base materials that would otherwise strip under load or repeated use.

This insert is suited for metric coarse thread repair and fabrication applications across industrial, automotive, aerospace, and general mechanical environments. The 9-1/2 free coils provide consistent thread engagement and load distribution once installed. The 304 stainless steel construction makes it appropriate for applications where corrosion resistance is a factor. It is sold as a single insert, with a minimum order quantity of 10 pieces.

Installation Notes

Installation requires a correctly sized Heli-Coil tap and a compatible insertion tool for M6 inserts - do not attempt installation with standard taps or improvised tooling. Ensure the host material is drilled and tapped to the proper Heli-Coil specification before insertion. After installation, the tang must be broken off using the appropriate tang break-off tool or needle-nose pliers. Wear eye protection during tang removal.
