Heli-coil A3585-2EN328 Locking Insert 8-32 Unc 2D

Product Description

The HELI-COIL A3585-2EN328 is a tangless screw-locking helical coil insert designed to create a durable, vibration-resistant threaded hole in a parent material. Manufactured from grade 18-8 stainless steel, this insert provides corrosion resistance in demanding service environments. It is rated for a maximum locking torque of 9 inch-pounds and a minimum breakaway torque of 1.50 inch-pounds, making it suitable for applications where fastener retention under vibration and cyclic loading is required. The tangless design eliminates the need for tang removal after installation, reducing assembly steps and the risk of debris in the threaded bore.

This insert is used wherever a reliable 8-32 UNC internal thread must be installed or repaired in metal, composite, or other parent materials. The 2D length-to-diameter ratio and 0.328-inch overall length make it appropriate for standard-depth threaded holes in light industrial, HVAC equipment, electrical enclosures, and mechanical assemblies. Installation is typically performed by maintenance technicians, assemblers, or field service professionals using compatible HELI-COIL installation tooling.

Key Features

• Tangless design eliminates post-installation tang removal for faster, cleaner assembly
• Grade 18-8 stainless steel construction for corrosion resistance
• Maximum locking torque of 9 inch-pounds for secure fastener retention under vibration
• Minimum breakaway torque of 1.50 inch-pounds ensures controlled removability
• 2D length-to-diameter ratio with 0.328-inch overall length suits standard threaded hole depths
• 8 free coils provide consistent thread engagement along the insert length

Compatibility

Designed as an OEM-style threaded insert for parent materials tapped to accept 8-32 UNC helical coil inserts with a minimum outside diameter of 0.205 inches and a maximum outside diameter of 0.220 inches.

Installation Notes

Installation requires a properly prepared and tapped parent hole sized for HELI-COIL 8-32 UNC inserts; use the correct drill and tap sizes specified for this insert series. A compatible tangless installation tool must be used - standard tang-type drivers are not suitable for tangless inserts. Power down or de-energize any equipment before thread repair work begins. Follow the equipment manufacturer and applicable industry guidelines for fastener torque requirements after insert installation.
