Heli-coil AT3585-06C276 Screw-locking Insert 6-32 Unc

Product Description

The HELI-COIL AT3585-06C276 is a screw-locking helical wire thread insert designed to create a secure, vibration-resistant internal thread in a parent material. Manufactured from Grade 304 stainless steel with a bright finish, this insert measures 0.276 inches in overall length and is sized for 6-32 UNC threads at a 2D length-to-diameter ratio. The tanged design allows for installation with a standard Heli-Coil driver tool. It delivers a maximum locking torque of 6 inch-pounds and a minimum breakaway torque of 1.0 inch-pound, making it suitable for assemblies where thread retention under load or vibration is required.

This insert is used in applications where stripped or soft parent-material threads need repair or reinforcement, or where a permanent locking thread is specified in new assembly work. Common installation environments include aerospace, automotive, industrial machinery, and electrical enclosure fabrication. The 6-32 UNC thread size is frequently found in light-gauge sheet metal assemblies and small fastener applications. The 304 stainless steel construction provides corrosion resistance in moderate-exposure environments. Sold as a single insert; minimum order quantity is 10 pieces.

Compatibility

Designed as a screw-locking thread insert for 6-32 UNC tapped holes requiring vibration-resistant thread retention in metallic and non-metallic parent materials.

Installation Notes

Installation is typically performed by a machinist, assembler, or maintenance technician using the appropriate Heli-Coil tap and installation driver for the 6-32 UNC thread series. The parent material must be tapped with the correct Heli-Coil STI tap before insert installation. After driving the insert to the specified depth, remove the tang using a tang break-off tool where required by the assembly specification. Follow applicable torque and thread engagement specifications from the engineering drawing or fastener standard governing the assembly.
