Heli-coil A1185-2EN328 Free Running Insert 8-32 Unc

Product Description

The HELI-COIL A1185-2EN328 is a free running helical wire thread insert designed to create strong, durable threads in tapped holes. Manufactured from 18-8 stainless steel, this tanged insert carries an 8-32 UNC thread size and measures 0.328 inches in overall length, placing it in the 2D length-to-diameter category. It installs into a specially prepared tapped hole to restore or reinforce damaged threads or to provide a hardened thread form in softer base materials. Technicians in mechanical, electrical, and light fabrication trades rely on these inserts for reliable thread repair and thread reinforcement work.

This insert is suited for use in both original equipment assembly and field repair applications. The 8-32 UNC thread size makes it a common choice for control panels, enclosures, and light structural assemblies where small-diameter machine screws are standard. The tanged design requires a standard HELI-COIL installation tool for proper seating and tang removal after installation. It is appropriate for residential and commercial applications wherever a durable stainless steel thread form is needed in aluminum, cast iron, magnesium, or other base materials.

Key Features

• 8-32 UNC thread size, suitable for common machine screw fastening applications
• 18-8 stainless steel construction provides corrosion resistance and long service life
• Tanged design for positive engagement during installation with a standard insertion tool

Compatibility

Designed as an OEM-style free running insert for applications requiring an 8-32 UNC thread form in a 2D configuration. Consult HELI-COIL tooling charts to confirm the correct tap size and installation tool for the base material being used.

Installation Notes

Installation should be performed by a qualified technician familiar with thread insert procedures. The host material must first be drilled and tapped with the correct HELI-COIL tap for the insert size before installation. Use a proper HELI-COIL insertion tool to drive the insert to the correct depth, then break off the installation tang using a tang break-off tool. Follow applicable equipment service standards and power down or de-energize any assembly before performing thread repair work on live equipment.
