1185-2CN246 - Helicoil ® Threaded Insert by Stanley ® Engineered Fastening

The Heli-Coil 1185-2CN246 is a high-strength wire thread insert designed to establish durable, permanent internal threads in low-strength parent materials such as aluminum, magnesium, and molded plastics. Precision-formed from high-quality cold-drawn 304 stainless steel wire with a diamond-shaped cross-section, this tanged, free-running insert conforms dynamically to tapped holes to maximize load distribution and alleviate stress concentration. It delivers outstanding corrosion resistance and long-term durability while eliminating common assembly issues like thread wear, stripping, and galling. Engineered to withstand high tensile loads and operational vibration, it provides a highly reliable, wear-resistant fastening solution across aerospace, electronics, and industrial applications.

High-Strength Thread Reinforcement Creates a permanently reinforced thread structure that prevents pulling, stripping, and shearing in soft base materials.

Corrosion and Heat Resistance Fabricated from premium-grade 304 stainless steel to maintain mechanical reliability in demanding environments.

Vibration-Proof Stability Utilizes expanding radial spring tension to anchor itself securely within the tapped hole, mitigating loosening caused by operational shock.

Wear-Resistant Longevity Significantly minimizes thread friction and wear, making it an excellent choice for assemblies requiring repeated installation cycles.
