Product Description
The Heli-Coil 1185-04CN224 by Stanley Engineered Fastening is a high-performance tanged free-running insert engineered to establish high-strength, permanent internal threads in low-density parent materials like aluminum, magnesium, and zinc die-castings. Precision cold-rolled from high-grade 304 stainless steel wire with a uniform diamond-shaped cross-section, this wire thread insert automatically expands elastically outward upon installation to establish a secure, spring-like retention force without requiring specialized keying or staking. Yielding a permanently wear-resistant thread, it distributes joint stresses evenly across the assembly to protect miniature hardware applications from thread stripping, galling, and structural failure under continuous fatigue.
Free-Running Profile Delivers a clean, conventional internal thread track that allows standard mating coarse bolts and fasteners to turn completely unhindered without added friction or torque resistance.
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 stripping.
