1185-3EN285 - Screw Threaded Insert by Helicoil Stanley Engineered Fastening

The Heli-Coil 1185-3EN285 by Stanley Engineered Fastening is a high-performance tanged free-running insert engineered to establish high-strength internal threads in lightweight, low-density parent materials like aluminum and magnesium alloys. Precision cold-rolled from specialized Nitronic 60 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. Its advanced material composition delivers exceptional anti-galling protection, completely eliminating the need for additional anti-seize lubricants when using stainless steel screws. This insert creates a permanently wear-resistant thread that yields optimized joint load distribution, shielding critical electronics, aerospace, and vacuum-environment assemblies against stripping and structural erosion.

Free-Running Profile Provides a smooth, conventional internal thread track that allows standard mating fine bolts to rotate unhindered without added torque resistance or specialized friction. Nitronic 60 Composition Offers superior inherent anti-galling performance and wear resistance, making it perfect for particle-free vacuum applications and eliminating the need for extra coatings or lubrication. Tanged Configuration Features a traditional driven installation tang that provides positive mechanical engagement with standard fine 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.
