Heli-coil A1084-5CN075 Free Running Insert M5 X 0.8

Product Description

The HELI-COIL A1084-5CN075 is a free running wire thread insert designed to create durable, load-bearing internal threads in tapped holes. Manufactured from 304 stainless steel with a bright, uncoated finish, it accepts M5 x 0.8 metric coarse threads and measures 7.5 mm (0.2953 inches) in overall length, placing it in the 1-1/2D length-to-diameter ratio category. The tanged design allows for installation with a standard HELI-COIL drive tool. This insert is used by machinists, maintenance technicians, and trade professionals to restore stripped threads or reinforce threads in soft parent materials.

This insert is suited for metric threaded applications in ferrous and non-ferrous parent materials across HVAC equipment housings, electrical enclosures, plumbing fixtures, and general mechanical assemblies. The 304 stainless steel construction provides corrosion resistance, making it appropriate for both indoor and outdoor service environments. With 6-7/8 free coils, the insert distributes thread load evenly across the bore, reducing the risk of pull-out or thread failure in high-vibration assemblies.

Installation Notes

Installation requires a correctly sized HELI-COIL tap to prepare the parent bore before the insert is driven in place. Power down or de-energize any equipment before performing thread repair on live assemblies. Use the appropriate mandrel-style drive tool to seat the insert flush with or slightly below the parent material surface. After installation, remove the tang using a tang break-off tool per standard wire insert procedure.
