Product Description
The Heli-Coil 1185-04CN168 is a high-strength free-running wire thread insert designed to establish permanent, wear-resistant internal threads in soft metals, alloys, and composite materials. Precision-formed from cold-drawn 304 stainless steel wire with a uniform diamond cross-section, this tanged insert features a spring-like helical profile that expands outward to grip tapped parent threads securely upon installation. Utilizing a streamlined free-running configuration, it permits male fasteners to thread smoothly without added prevailing torque or rotational drag until final clamp load is achieved. The dynamic wire coils flex independently to distribute load stresses evenly across all engaged threads, providing exceptional stripping protection, corrosion resistance, and structural joint 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 Resilience 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.
