Product Description
The Heli-Coil 1185-8CN1000 is a heavy-duty free-running wire thread insert designed to establish high-strength, permanent internal threads in soft metals, aluminum castings, and structural host materials. Precision-coiled from work-hardened 304 stainless steel wire with a diamond cross-section, this tanged insert features a resilient helical profile that expands outward upon installation to anchor securely inside tapped parent holes. Operating in an unobstructed free-running design, it permits 1/2-13 UNC male hardware to turn smoothly through the assembly without added prevailing torque or rotational drag until final clamping force is applied. Its 2D nominal length provides deep thread engagement to maximize tensile load capacity, delivering supreme stripping protection, corrosion resistance, and joint fatigue strength.
Free-Running Dynamic Rotation Delivers an uninhibited internal thread path that lets male fasteners spin freely through the coil without added torque resistance or installation drag.
Integrated Driving Tang Built with a robust drive tang on the leading coil to ensure positive tool engagement and controlled, accurate insertion depth setting.
304 Stainless Steel Construction Manufactured from work-hardened, corrosion-resistant steel wire to build a wear-proof thread foundation that protects soft host metals against stripping.
Maximized Tensile Load Distribution The 2D nominal length disperses clamping forces evenly across extra thread engagements, compensating for pitch and angle variances while boosting pull-out strength.
