1084-6EN090 by HELI-COIL

The Heli-Coil 1084-6EN090 by Stanley Engineered Fastening is a premium tanged free-running metric insert meticulously designed to establish permanent, high-strength internal threads in low-density parent materials such as aluminum and magnesium alloys. Precision cold-rolled from specialized Nitronic 60 stainless steel wire with a precise 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. Its advanced material composition delivers exceptional anti-galling protection, completely eliminating the need for additional anti-seize lubricants when using stainless steel screws. This metric wire insert creates a permanently wear-resistant thread that optimizes joint load distribution and handles elastic thermal expansion, rendering it an ideal solution for critical clean-room, particle-free vacuum, and high-fatigue assemblies.

Free-Running Profile Provides a smooth, conventional internal thread track that allows standard metric mating bolts to rotate completely unhindered without added torque resistance.

Nitronic 60 Composition Offers superior inherent anti-galling performance and wear resistance, making it perfect for vacuum applications while eliminating the need for extra coatings or lubrication.

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

Resilient Wire Construction Utilizes a continuous helically wound diamond profile that distributes stresses evenly across the tapped parent material to shield assemblies from thread stripping and wear.
