Product Description
The Heli-Coil 1084-3CN090 is a high-precision free-running wire thread insert designed to build durable, wear-resistant metric threads in aluminum, magnesium, and soft alloy materials. Precision-formed from work-hardened 304 stainless steel wire with a uniform diamond-shaped cross-section, this tanged insert features a flexible helical structure that contracts during installation and expands outward to lock into tapped parent threads. Operating in a free-running configuration, it allows standard male metric fasteners to spin smoothly without added rotational drag or prevailing torque. The dynamic wire coils adjust to pitch and angle variances, distributing bolt loads evenly across the thread network to deliver supreme stripping protection, corrosion resistance, and joint strength.
Free-Running Dynamic Rotation Maintains an unobstructed internal thread path that lets male metric bolts turn freely through the coil without drag or installation resistance.
Integrated Driving Tang Features a precision-engineered drive tang on the leading coil to ensure positive tool engagement and rapid, controlled insertion depth setting.
304 Stainless Steel Construction Cold-drawn from work-hardened austenitic stainless steel wire to protect soft host materials against internal thread stripping, galling, and mechanical wear.
Uniform Load Distribution Flexible helical coils adapt to pitch and angle tolerances in tapped holes, dispersing concentrated tensile forces evenly across all engaged threads.
