Product Description
The Heli-Coil 1084-8CN080 by Stanley Engineered Fastening is a high-strength tanged free-running metric insert designed to establish permanent, high-integrity internal threads in low-density parent metals 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. Yielding a permanently wear-resistant thread, it balances joint stress distribution evenly to protect metric M8 hardware assemblies from thread stripping, galling, and structural failure under continuous fatigue.
Free-Running Profile Provides a clean, conventional internal thread track that allows standard metric mating bolts and screws to rotate completely unhindered without added friction or torque resistance.
Tanged Configuration Features a traditional driven installation tang that provides positive mechanical engagement with standard metric mandrels for controlled and highly accurate depth seating into tapped holes.
High Structural Integrity Compensates for pitch and angle variances within tapped parent metals, dispersing concentrated joint loads evenly to elevate overall assembly fatigue life.
Resilient Wire Construction Utilizes a continuous helically wound diamond profile that handles thermal expansion and contraction elastically while safeguarding against thread stripping and wear.
