Product Description
The Heli-Coil 1185-3CN285 is an extra-length, precision-engineered free-running wire thread insert built to create high-strength, wear-resistant internal threads in soft host materials. Precision-formed from work-hardened 304 stainless steel wire with a uniform diamond cross-section, this tanged insert features a resilient helical profile that expands outward to anchor firmly within tapped holes. Featuring an unobstructed free-running design, it allows #10-24 male hardware to turn smoothly without added rotational drag or prevailing torque until final torque is applied. Its 3D nominal length provides deep thread engagement to maximize pull-out strength, delivering supreme stripping protection, corrosion resistance, and joint fatigue life in demanding structural applications.
Free-Running Dynamic Rotation Delivers an uninhibited internal thread path that lets male fasteners turn freely through the helical coil without drag or rotational friction.
Integrated Driving Tang Features a robust drive tang on the leading coil to provide positive tool engagement for controlled and accurate insertion depth setting.
304 Stainless Steel Construction Manufactured from work-hardened, corrosion-resistant steel wire to build a durable thread foundation that protects soft host metals against stripping, galling, and wear.
Maximized Tensile Load Distribution The extended 3D length distributes tension across extra thread engagements, compensating for pitch and angle variances while dramatically boosting joint pull-out resistance.
