T1185-4E375 by HELI-COIL

The Heli-Coil T1185-4E375 by Stanley Engineered Fastening is a high-performance tangless free-running insert engineered to establish strong, permanent internal threads in lightweight parent metals like aluminum, magnesium, and zinc die-castings. Precision cold-rolled from high-strength Nitronic 60 stainless steel wire, this thread insert features an advanced tangless bi-directional design that completely eliminates installation tangs, eradicating foreign object debris (FOD) risks and eliminating tang break-off steps in critical assemblies. Nitronic 60 wire provides exceptional inherent resistance to thread galling and friction wear, eliminating the need for extra anti-seize lubricants when paired with stainless steel screws. Yielding a permanently wear-resistant thread, it disperses joint stress evenly to safeguard 1/4-20 coarse hardware configurations under continuous fatigue.

Tangless Bi-Directional Design Eliminates installation tangs to prevent foreign object debris (FOD) issues, allowing quick, non-destructive installation and easy removal or adjustment from either end.

Nitronic 60 Construction Offers superior inherent anti-galling performance and wear resistance, making it ideal for high-temperature or vacuum environments without extra coatings.

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

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