Product Description
The Heli-Coil 1185-02CN129 is a high-strength, military-grade free-running wire thread insert designed to establish permanent, wear-resistant internal threads in soft or lightweight host materials. Precision-formed from cold-drawn 304 stainless steel wire with a diamond-shaped cross-section, this tanged insert automatically adjusts to meet the thermal expansion and contraction profiles of parent metals. The design features a low-profile free-running configuration that allows smooth, unrestricted rotation of the male fastener until final torque is reached. It effectively distributes load stresses evenly across the tapped hole, providing reliable stripping protection and structural thread reinforcement under operational load.
Free-Running Configuration Allows the mating bolt to spin freely through the helical profile without impedance until final installation torque is applied.
Standard Driving Tang Equipped with a strong, integrated drive tang on the leading coil to ensure precise installation tool engagement and rapid depth setting.
Premium CRES Composition Constructed from corrosion-resistant steel that is work-hardened to maximize tensile strength and shield threads against premature stripping or galling.
Optimized Load Distribution Dynamically expands within the tapped host hole to eliminate stress concentrations and deliver uniform clamping pressure across every single thread coil.
