1185-2EN164 - Screw Threaded Insert by Helicoil Stanley Engineered Fastening

The Heli-Coil 1185-2EN164 by Stanley Engineered Fastening is a high-strength tanged free-running insert engineered to establish permanent, high-integrity internal threads in lightweight parent materials like aluminum, magnesium, and zinc die-castings. Precision cold-rolled from high-performance Nitronic 60 stainless steel wire with a uniform diamond 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. Nitronic 60 provides exceptional inherent resistance to thread galling, completely eliminating the need for additional anti-seize lubricants when paired with stainless steel screws. Yielding a permanently wear-resistant thread, it balances joint stress distribution evenly to shield #8-32 hardware configurations from thread stripping, friction wear, and structural failure under continuous fatigue.

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

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

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.
