3585-04CN112SF by HELI-COIL

The Heli-Coil 3585-04CN112SF by Stanley Engineered Fastening is a high-performance tanged screw-locking insert provided in a strip-feed packaging format for high-volume automated assembly. Cold-rolled from premium 304 stainless steel wire with a uniform diamond-shaped cross-section, this wire thread insert automatically adapts to pitch and angle variances for optimized joint load distribution in soft parent materials like aluminum and magnesium. Its advanced screw-locking configuration incorporates a series of specialized straight chord segments on the internal coils that exert a resilient self-locking torque on the male fastener, preventing rotational loosening caused by severe shock and vibration without requiring lock-washers or auxiliary locking devices. Yielding a permanently wear-resistant thread, it protects #4-40 hardware joints against thread stripping, galling, and fatigue failure.

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.

Strip-Feed Format Supplied on continuous strips to optimize production throughput and support automated high-speed installation equipment.

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.

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