Heli-coil A3585-06CN276 Screw-lock Insert 6-32 Unc 2D

Product Description

The HELI-COIL A3585-06CN276 is a tangless screw-locking helical wire insert designed to create a durable, vibration-resistant threaded hole in a parent material. It accepts a 6-32 UNC fastener and installs to an overall length of 0.276 inches, providing a 2D length-to-diameter ratio for reliable thread engagement. The insert is manufactured from Grade 304 stainless steel with a bright finish, making it suitable for applications where corrosion resistance and cleanliness are required. Maximum locking torque is 6 in/lb, with a minimum breakaway torque of 1.00 in/lb. This type of insert is specified by mechanical assemblers, MRO technicians, and production machinists working in aerospace, industrial, and general manufacturing environments.

This insert is suited for applications requiring a precision locking thread in new or stripped 6-32 UNC tapped holes. The tangless design eliminates the need for tang break-off after installation, reducing debris risk in blind holes and critical assemblies. It is commonly used in sheet metal, aluminum, and other softer parent materials where thread stripping is a concern, as well as in environments where vibration could cause fastener loosening over time.

Key Features

• Tangless design eliminates post-installation tang removal, reducing debris in blind holes
• Grade 304 stainless steel construction provides corrosion resistance and long service life
• 6-32 UNC thread size with 2D length-to-diameter ratio for solid thread engagement
• Overall length of 0.276 inches fits standard 2D insert pocket depth
• Maximum locking torque of 6 in/lb with minimum breakaway torque of 1.00 in/lb
• Bright finish; 6-7/8 free coils for consistent locking performance

Compatibility

Designed as an OEM-style replacement or new-installation threaded insert for 6-32 UNC tapped holes in parent materials requiring a helical wire locking insert with a 2D engagement length.

Installation Notes

Installation is performed by machinists or assembly technicians using a HELI-COIL compatible tangless installation tool matched to the 6-32 thread size. The parent material must first be drilled and tapped to the correct HELI-COIL insert tap specification before the insert is driven to the proper seated depth. Ensure the parent hole is clean and free of chips or debris before installation. Do not use standard tang-type installation tools with tangless inserts, as tool compatibility is required for correct seating.
