Product Description
The Heli-Coil 1084-8EN160 is a heavy-duty free-running wire thread insert crafted from Nitronic 60 stainless steel to deliver superior anti-galling protection and permanent thread reinforcement in metric applications. Precision-wound from cold-drawn wire with a diamond-shaped cross-section, this tanged insert contracts during tool engagement and expands outward to anchor securely inside tapped holes. Specialized Nitronic 60 alloy properties prevent cold welding, seizing, and thread galling during rapid or high-temperature assembly without requiring secondary coatings or dry lubricants. Operating in an uninhibited free-running configuration, it allows M8x1.25 male hardware to spin smoothly through the coil, providing outstanding stripping protection and uniform stress distribution across soft parent metals.
Nitronic 60 Anti-Galling Alloy High-alloy austenitic stainless steel formulation eliminates thread seizure, galling, and cold welding during high-speed assembly or elevated-temperature service.
Free-Running Dynamic Rotation Delivers an unobstructed internal thread path that allows standard metric bolts to spin freely through the coil without added drag or torque resistance.
Integrated Driving Tang Features a precision drive tang on the leading coil for positive tool engagement and accurate, repeatable insertion depth control.
Uniform Load Distribution Flexible helical coils adapt to pitch and angle tolerances, dispersing tensile loads evenly across all engaged threads to maximize joint fatigue strength.
