1185-8EN500 - Screw Threaded Insert by Helicoil Stanley Engineered Fastening

The Heli-Coil 1185-8EN500 by Stanley Engineered Fastening is a high-strength tanged free-running insert designed to create permanent, heavy-duty internal threads in low-density parent metals like aluminum, magnesium, and cast iron. 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 disperses joint stress evenly across the tapped parent material to shield heavy structural assemblies from thread stripping, friction wear, and fatigue failure.

Free-Running Profile Provides a smooth, conventional internal thread track that allows standard mating coarse 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 or high-temperature environments while eliminating the need for extra coatings or lubrication.

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

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