3585-2CN164 - Helicoil ® Threaded Insert by Stanley ® Engineered Fastening

The Heli-Coil 3585-2CN164 by Stanley Engineered Fastening is a high-performance tanged screw-locking insert engineered to provide durable, high-strength internal threads in lightweight parent materials such as aluminum and magnesium. Cold-rolled from premium 304 stainless steel wire with a uniform diamond-shaped cross-section, this wire thread insert automatically adjusts to pitch and angle variances for optimized joint load distribution. Its advanced screw-locking configuration incorporates a series of straight chord segments on the internal coils that exert a resilient self-locking torque on the male fastener, preventing loosening caused by severe shock and vibration without requiring lock-washers or auxiliary locking devices. Yielding a permanently wear-resistant thread, it protects fine hardware joints against thread stripping, galling, and rotational back-out.

Screw-Locking Mechanism Grips the male bolt or screw with a series of specialized straight segments on the internal coils, ensuring a secure, vibration-proof joint without requiring lock-washers or auxiliary locking devices.

Tanged Configuration Features a traditional driven installation tang that provides positive mechanical engagement with standard mandrels for controlled and highly accurate depth seating into tapped holes.

High Structural Integrity Compensates for pitch and angle variances within tapped parent metals, dispersing concentrated joint loads evenly to elevate overall assembly fatigue life.

Resilient Wire Construction Utilizes a continuous helically wound diamond profile that handles thermal expansion and contraction elastically while safeguarding against thread stripping and wear.
