Product Description
The Heli-Coil 1185-04CN112 is a high-strength free-running wire thread insert engineered to establish permanent, wear-resistant internal threads in lightweight 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 retention design that expands outward against the host material's tapped threads upon seating. Utilizing a streamlined free-running configuration, it allows male fasteners to thread smoothly without added prevailing torque or rotational resistance until final clamping force is applied. The dynamic wire structure distributes load stresses evenly across the assembly, providing exceptional stripping protection, corrosion resistance, and structural joint durability.
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.
