Heli-coil A1185-06EN276 6-32 Unc Free Running Insert

Product Description

The HELI-COIL A1185-06EN276 is a free running helical wire thread insert designed to create or restore strong, wear-resistant internal threads in parent material that is softer or damaged. Manufactured from 18-8 stainless steel, this insert provides corrosion resistance and durability in demanding fastening applications. It carries a 6-32 UNC thread profile with an overall insert length of 0.276 inches, representing a 2D length-to-diameter ratio. The tanged design allows for standard installation tooling and removal of the tang once the insert is seated. This type of insert is used by machinists, maintenance technicians, and assembly professionals across a wide range of industries.

This insert is suited for applications where a 6-32 UNC internal thread needs to be installed in a drilled and tapped hole or where an existing thread has been stripped and must be repaired. The 0.276 inch overall length and 2D ratio make it appropriate for shallow boss depths and thin-section materials. Stainless steel construction makes it a sound choice for environments with moisture exposure or mild chemical contact. It is sold as a single insert with a minimum order quantity of 5 units.

Key Features

• 6-32 UNC thread size for standard inch-series fastener compatibility
• 18-8 stainless steel construction for corrosion resistance

Compatibility

Designed as an OEM-style free running insert for use in any parent material tapped to accept a 6-32 UNC helical insert, including aluminum, magnesium, cast iron, and plastics where thread reinforcement or repair is required.

Installation Notes

Installation requires a properly sized HELI-COIL tap and insert tool matched to the 6-32 thread size. The parent hole must be drilled and tapped to the correct HELI-COIL oversize specification before the insert is driven in. Once the insert is fully seated flush with or below the surface, break off the installation tang using a tang break-off tool. Follow all applicable mechanical assembly standards and torque specifications for the fastener being used with the installed insert.
