Heli-coil A3585-06EN276 Screw-locking Insert 6-32 Unc

Product Description

The HELI-COIL A3585-06EN276 is a screw-locking helical wire insert designed to create a secure, vibration-resistant threaded hole in a parent material. It accepts a 6-32 UNC fastener and installs to a depth of 0.276 inches overall, providing a 2D length-to-diameter ratio. Manufactured from 18-8 stainless steel, it delivers corrosion resistance suited to demanding industrial and mechanical environments. A locking feature built into the coil prevents fastener back-out under vibration or dynamic loading. Machinists, maintenance technicians, and assembly professionals typically install these inserts during new fabrication or thread repair operations.

This insert is applied wherever a durable 6-32 UNC internal thread is needed in softer parent materials such as aluminum, magnesium, or plastic, or where a worn or damaged thread must be restored to original specification. It is well suited to precision equipment, electronics enclosures, aerospace assemblies, and general industrial machinery where thread integrity and resistance to loosening are critical requirements. The tangless design is noted in the raw title; however, the technical attribute data identifies this insert as tanged, so verify the specific variant against the MPN before installation.

Key Features

• 6-32 UNC thread size for compatibility with standard inch-series fasteners
• 2D length-to-diameter ratio with 0.276 inches overall insert length
• 18-8 stainless steel construction for corrosion resistance
• Screw-locking design resists vibration-induced fastener loosening
• Maximum locking torque of 6 in/lb and minimum breakaway torque of 1 in/lb
• Outside diameter range of 0.178 inches minimum to 0.193 inches maximum
• 6-7/8 free coils for consistent thread engagement

Compatibility

Designed as an OEM-style replacement or new-installation insert for any application requiring a 6-32 UNC internal threaded insert in a drilled and tapped parent hole prepared to HELI-COIL installation specifications.

Installation Notes

Installation requires a correctly sized STI (Screw Thread Insert) tap to prepare the parent hole to the proper oversize dimension before insert installation. Power down or de-energize any equipment before performing thread repair or installation work. Use the manufacturer-specified installation tool to drive the insert to the correct depth without distorting the coils. Follow applicable facility safety and torque verification procedures after installation to confirm proper seating and locking performance.
