Product Description
The Heli-Coil 1185-2CN410 is a high-strength free-running wire thread insert designed to establish permanent, wear-resistant internal threads in soft metals, aluminum, and composite host materials. Precision-formed from cold-drawn 304 stainless steel wire with a uniform diamond cross-section, this tanged insert features a spring-like helical structure that expands outward to grip tapped parent threads securely upon installation. Utilizing an unobstructed free-running configuration, it permits male fasteners to thread smoothly through the coil without added prevailing torque or rotational friction until final seating. The dynamic wire coils flex independently to distribute load stresses evenly across the assembly, providing exceptional stripping protection, corrosion resistance, and joint fatigue strength.
Free-Running Dynamic Rotation Delivers an unobstructed thread path that allows standard male hardware to spin freely through the helical profile without added friction or torque resistance.
Integrated Drive Tang Built with a robust drive tang on the leading coil to provide positive tool engagement for controlled and accurate insertion depth setting.
304 Stainless Steel Construction Manufactured from work-hardened, corrosion-resistant steel wire to protect soft host materials against internal thread stripping, galling, and wear.
Balanced Stress Distribution Compensates for pitch and angle variances within tapped parent metals, dispersing concentrated joint loads evenly to maximize overall fatigue life.
