Product Description
The Heli-Coil 3585-04CN112 by Stanley Engineered Fastening is a high-performance screw-locking tanged insert engineered to establish permanently durable, high-strength internal threads in low-density parent materials. Precision cold-rolled from high-grade 304 stainless steel wire with a precise diamond-shaped cross-section, this wire thread insert compensates for pitch and angle variances to optimize joint load distribution. Its specialized screw-locking configuration incorporates one or more straight segments or chords on the coils that exert a resilient, self-locking torque onto the male fastener, preventing it from backing out or loosening under intense vibration or thermal shock. This insert creates a permanently wear-resistant thread that shields critical electronic, automotive, and industrial assemblies from stripping and structural erosion.
Screw-Locking Mechanism Grips the male bolt or screw with a resilient internal locking thread, ensuring a secure, vibration-proof joint without the need for lock-washers or auxiliary locking devices.
Tanged Configuration Features a traditional driven installation tang that provides positive mechanical engagement with the mandrel during the seating process into the tapped hole.
High Structural Integrity Automatically expands outward upon installation to anchor itself permanently, providing wear-resistant threads that dynamically adapt to material expansion and contraction.
Resilient Wire Construction Utilizes a continuous helically wound diamond profile that distributes stresses evenly across the tapped parent material to shield assemblies from thread stripping and wear.
