Product Description
The Heli-Coil 1191-3CN380 is a high-performance wire thread insert meticulously engineered to provide exceptional structural integrity and high-strength internal threads in softer parent materials. Precision-wound from high-quality 304 stainless steel wire with a distinctive diamond-shaped cross-section, this tanged, free-running insert conforms dynamically to tapped holes to maximize load distribution and alleviate stress concentration. It delivers superb corrosion resistance and long-term durability while entirely eliminating common assembly issues such as thread wear, stripping, and galling. Designed to withstand severe vibrational impact and extreme thermal fatigue, it yields a permanent, wear-resistant fastening solution perfect for high-reliability manufacturing and assembly.
High-Strength Thread Reinforcement Creates a permanently reinforced thread structure that prevents pulling, stripping, and shearing in low-strength base metals.
Corrosion and Heat Resistance Fabricated from premium-grade 304 stainless steel to maintain mechanical reliability and structural integrity in demanding environmental conditions.
Vibration and Shock Protection Utilizes expanding radial spring tension to anchor itself securely within tapped holes, preventing loosening caused by operational shock.
Wear-Resistant Longevity Significantly minimizes thread wear and friction, making it an ideal choice for assemblies that require repeated installation and breakdown cycles.
