Heli-coil R1185-2 Free Running Insert 8-32 Unc Stainless

Product Description

The HELI-COIL R1185-2 is a free running wire thread insert designed to create or restore durable internal threads in tapped holes. Manufactured from stainless steel with a bright, uncoated finish, this tanged insert measures 0.246 inches overall length and is sized for 8-32 UNC threads. The coiled wire design distributes load across multiple thread engagement points, extending the service life of the parent material. Installers in HVAC, electrical, plumbing, and general mechanical trades use these inserts to repair stripped threads or to reinforce soft-metal and low-strength parent materials without replacing the entire component.

This insert is suited for applications where a permanent, high-strength thread repair or installation is required in metal housings, equipment enclosures, brackets, and similar components. The 1-1/2D length-to-diameter ratio and 6 free coils provide solid thread engagement for 8-32 fasteners in both light-duty and moderate-load assemblies. Each package contains 12 inserts, making it practical for technicians who perform multiple repairs on a service call or in a shop environment.

Compatibility

Designed as a standard OEM-style free running thread insert for use in any parent material tapped to accept an 8-32 UNC HELI-COIL style insert, using the corresponding installation tool and tap specified for this insert size.

Installation Notes

Installation requires a HELI-COIL specification tap to prepare the parent hole to the correct oversize dimension before inserting. A proper installation mandrel or driver tool should be used to wind the insert into the tapped hole to the correct depth. After seating, the installation tang must be broken off using a tang break-off tool or needle-nose pliers. Always follow applicable torque and fastener specifications for the assembly being serviced.
