3585-2CN328 - Helicoil ® Threaded Insert by Stanley ® Engineered Fastening

The Heli-Coil® 3585-2CN328 is a screw-locking, tanged wire thread insert precision-formed from 304 stainless steel. Designed to form high-strength, permanent #8-32 UNC threads in soft parent materials, this insert features a series of resilient locking coils that exert strong radial pressure on the mating fastener to prevent loosening caused by severe shock and vibration. Its diamond-shaped helical wire structure provides exceptional corrosion resistance and wear protection, ensuring long-term joint integrity without the need for lock washers or secondary locking devices.

304 Stainless Steel Construction provides outstanding corrosion resistance, high tensile strength, and reliable durability in demanding environments.

Screw-Locking Mechanism utilizes internal straight-segment coils to securely grip mating bolts, preventing rotational loosening under dynamic vibration.

Integrated Drive Tang facilitates fast, precise insertion into standard tapped holes using tanged installation tooling.

#8-32 UNC Coarse Threading repairs worn tapped threads or reinforces soft metals like aluminum and magnesium.

2D Nominal Length Ratio maximizes engagement depth to deliver superior pull-out strength and load distribution.
