Product Description
The Heli-Coil 1185-04CN112SF is a high-precision free-running wire thread insert packaged on continuous plastic reels in a strip-feed format for high-speed automated and power-tool installation. Formed from cold-drawn 304 stainless steel wire with a uniform diamond-shaped cross-section, this tanged insert creates permanent, wear-resistant internal threads in soft metals, aluminum, and composite structures. Featuring an uninhibited free-running configuration, it allows male fasteners to thread smoothly without added prevailing torque or rotational friction until final clamping load is established. The strip-feed system accelerates production workflows, maximizing assembly throughput and reducing manual handling while providing ultimate joint reliability and thread stripping protection.
Strip-Feed Packaging Continuous reel-mounted format optimized for automated or power installation tooling, significantly increasing production efficiency and reducing operator loading time.
Free-Running Dynamic RotationDelivers an uninhibited thread path that allows standard male hardware to spin freely through the helical profile without added friction or torque resistance.
Integrated Drive Tang Built with a robust drive tang on the leading coil to provide positive tool engagement for controlled and accurate insertion depth setting.
304 Stainless Steel Resilience Manufactured from work-hardened, corrosion-resistant steel wire to protect soft host materials against internal thread stripping, galling, and wear.
