1185-2CN492 - Helicoil ® Threaded Insert by Stanley ® Engineered Fastening

The Heli-Coil 1185-2CN492 by Stanley Engineered Fastening is a high-strength tanged free-running insert designed to establish permanent, high-integrity internal threads in lightweight parent materials like aluminum, magnesium, and zinc die-castings. Precision cold-rolled from high-grade 304 stainless steel wire with a uniform diamond-shaped cross-section, this wire thread insert automatically expands elastically outward upon installation to establish a secure, spring-like retention force without requiring keying or staking. Engineered with an extended 3D length-to-diameter ratio, it maximizes thread engagement depth to distribute joint stress over a broader engagement zone. Yielding a permanently wear-resistant thread, it shields #8-32 hardware configurations from thread stripping, galling, and structural failure under continuous fatigue.

Free-Running Profile Provides a clean, conventional internal thread track that allows standard mating coarse bolts and screws to rotate completely unhindered without added friction or torque resistance.

Extended 3D Engagement Length Provides maximum load transfer depth in soft alloys, dramatically increasing tensile strength and pull-out resistance for critical joint connections.

Tanged Configuration Features a traditional driven installation tang that provides positive mechanical engagement with standard mandrels for controlled and highly accurate depth seating into tapped holes.

Resilient Wire Construction Utilizes a continuous helically wound diamond profile that handles thermal expansion and contraction elastically while safeguarding against thread stripping and wear.
