Heli-coil A1185-6EN562 Insert 3/8-16 Unc 0.562 in Ss

Product Description

The HELI-COIL A1185-6EN562 is a free running, tanged wire thread insert designed to create or restore strong internal threads in a host material. Manufactured from stainless steel, this insert measures 0.562 inches overall length with a 3/8-16 UNC thread size and a 1-1/2D length-to-diameter ratio. It installs into a prepared, tapped hole and forms a resilient coiled thread that distributes load across multiple contact points. Machinists, maintenance technicians, and assembly professionals use this type of insert to repair stripped threads or to build durable threaded interfaces in softer base materials. The tanged design allows standard installation tooling to drive and seat the insert correctly.

This insert is suited for thread repair and new-build applications across industrial, mechanical, and maintenance environments. It is appropriate for use in aluminum, cast iron, magnesium, plastics, and other materials where a stronger, more wear-resistant thread form is needed. The 3/8-16 UNC thread size covers a wide range of fastener applications in general mechanical assembly. A minimum order quantity of 5 units applies to this part.

Key Features

• 3/8-16 UNC thread standard for broad fastener compatibility
• 0.562 inch overall length with a 1-1/2D length-to-diameter ratio
• Stainless steel construction for corrosion resistance and durability
• Tanged design compatible with standard HELI-COIL installation tools
• 7-1/4 free coils provide consistent thread engagement across the insert length

Compatibility

Designed as an OEM-style free running threaded insert for use in any application requiring a 3/8-16 UNC internal thread repair or installation in a prepared host material.

Installation Notes

Installation requires a correctly sized HELI-COIL tap and a compatible installation tool matched to the 3/8-16 thread size. The host material must be drilled and tapped to the HELI-COIL insert tap specification before the insert is driven into place. After installation, the installation tang is broken off using a tang break-off tool. Follow manufacturer installation guidelines and applicable mechanical assembly standards for thread locking or torque requirements specific to the application.
