Heli-coil 1084-6CN060S Free Running Insert M6x1 6mm Ss

Product Description

The HELI-COIL 1084-6CN060S is a free-running helical wire thread insert designed to restore or reinforce M6 x 1 metric coarse threads in parent materials that are soft, damaged, or otherwise prone to thread failure. The insert measures 6 millimeters in overall length (0.2362 inches), corresponding to a 1D length-to-diameter ratio. Constructed from 304 stainless steel, it provides corrosion resistance and lasting thread integrity in demanding service environments. The tanged design aids installation with a standard insertion tool. This insert is a single-unit item typically used by mechanics, machinists, and maintenance technicians working on precision thread repair.

Free-running inserts like the 1084-6CN060S are used wherever a threaded hole requires reinforcement or repair without locking the fastener in place. Suitable for both production and field repair applications, this insert is commonly installed in automotive, aerospace, industrial equipment, and general mechanical assemblies. The M6 x 1 metric coarse thread profile fits a wide range of standard fastener applications. With 4 free coils, the insert distributes load across the thread engagement length to reduce stress concentration and extend the service life of the tapped hole.

Key Features

• M6 x 1 metric coarse thread profile for broad fastener compatibility
• 6 millimeter overall insert length with a 1D length-to-diameter ratio
• 304 stainless steel construction for corrosion resistance in harsh environments
• Tanged design for positive installation tool engagement
• 4 free coils for distributed load across the thread engagement length
• Free-running design allows normal fastener installation and removal without locking

Compatibility

Designed as an OEM-style thread repair insert for any M6 x 1 metric coarse tapped hole requiring reinforcement or restoration in metal parent materials.

Installation Notes

Installation is performed by machinists or maintenance technicians using a HELI-COIL series insertion tool matched to the M6 x 1 thread size. The parent material must be drilled and tapped to the correct HELI-COIL oversize tap dimension before insert installation. After the insert is driven to the correct depth, the installation tang is broken off using a tang break-off tool. Always verify thread engagement depth and inspect the installed insert with a go/no-go gauge where tolerances are critical.
