Heli-coil R1084-11 Free Running Insert M11 X 1.5 6 Pack

Product Description

The HELI-COIL R1084-11 is a free-running helical wire thread insert designed to repair or reinforce M11 x 1.5 metric coarse internal threads in a wide range of base materials. Manufactured from stainless steel with a bright, uncoated finish, the insert measures 16.5 mm in overall length and carries a 1-1/2D length-to-diameter ratio. It ships as a package of 6 inserts. Tanged design allows for standard installation tooling and post-install tang break-off. This insert is used by machinists, maintenance technicians, and field service professionals who need reliable thread repair or thread reinforcement without replacing the parent part.

Free-running inserts like the R1084-11 are suited for applications where a smooth, free-turning engagement between mating fasteners is required. Common install scenarios include thread repair in aluminum, cast iron, magnesium, and plastic housings found in HVAC equipment, pumps, compressors, motors, and other mechanical assemblies. The stainless steel construction provides corrosion resistance and durability in environments where base material threads have stripped or worn. Each package contains 6 inserts, making it practical for both single repairs and small production runs.

Installation Notes

Installation requires a matching HELI-COIL tap and installation tool sized for M11 x 1.5 inserts. Power down or de-energize any equipment before performing thread repair work. After driving the insert to the correct depth, break off the installation tang using a tang break-off tool. Follow all applicable equipment service procedures and workplace safety standards during installation.
