Product Description
The Heli-Coil 1185-2CN246SF by Stanley Engineered Fastening is a premium tanged free-running insert engineered to provide durable, high-strength internal threads in soft or low-strength parent materials. Fabricated from cold-rolled 304 stainless steel wire precision-formed into a diamond-shaped cross-section, this wire thread insert automatically expands outward when installed into a tapped hole to securely anchor itself without the need for staking, keying, or swaging. Designed for high-volume manufacturing efficiency, it features a convenient strip-feed packaging configuration that optimizes automated or semi-automated power installation tools. This insert effectively balances joint load distribution by eliminating stress concentrations, creating a permanently wear-resistant thread that defends assemblies against stripping, corrosion, and thread erosion.
Free-Running Design Provides a clean, conventional internal thread that allows standard bolts and fasteners to turn freely through the precision-formed profile.
Strip-Feed Packaging Delivers the inserts aligned on a plastic strip to significantly accelerate assembly throughput when used with power installation tools.
Tanged Configuration Features a traditional driven mandrel installation tang that ensures predictable depth control and simple engagement during the seating process.
Resilient Wire Construction Utilizes a continuous helically wound diamond profile that dynamically adjusts to thermal expansion and vibration to prevent joint loosening.
