3585-06CN138SF by HELI-COIL

The Heli-Coil 3585-06CN138SF by Stanley Engineered Fastening is a heavy-duty screw-locking tanged insert engineered to form high-strength, permanent internal threads in soft metals and low-strength parent materials. Precision-rolled from premium cold-drawn 304 stainless steel wire with a diamond-shaped cross-section, this wire thread insert features an exclusive screw-locking configuration that uses a series of straight segments or chords on the coils to apply a resilient, self-locking torque to the male fastener, preventing it from loosening under extreme vibration, impact, or thermal shock. Designed to maximize high-volume assembly line productivity, it features a convenient strip-feed packaging layout that optimizes compatibility with automated power installation tools. By distributing joint loads evenly and eliminating localized stress concentrations, this insert provides a permanently wear-resistant thread that thoroughly shields critical industrial, automotive, and electronic assemblies from stripping and thread wear.

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

Strip-Feed Layout Aligns wire thread inserts on a continuous plastic strip to dramatically optimize manufacturing throughput when paired with high-speed automated power tools.

Tanged Configuration Features a traditional driven installation tang that provides positive mechanical engagement with the mandrel for highly accurate depth seating.

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