1185-2EN246 - Screw Threaded Insert by Helicoil Stanley Engineered Fastening

The Heli-Coil Stanley Engineered Fastening 1185-2EN246 is a high-performance wire thread insert designed to establish durable, free-running internal threads in low-strength parent materials. Crafted from premium Nitronic 60 stainless steel, this insert offers superior gall resistance, making it ideal for pairing with stainless steel screws and operating cleanly in demanding, vacuum environments without the need for additional plating. Its precision design enables the spring-like coils to automatically adapt to thermal expansion and contraction while remaining permanently anchored against the tapped hole, providing a wear-resistant installation that continuously safeguards against vibration loosening.

Free-Running Tanged Design delivers a completely smooth internal thread path while leveraging outward radial tension to anchor itself permanently in the host material.

Nitronic 60 Stainless Steel construction prevents thread wear and galling, making it exceptionally reliable when used in assemblies with stainless steel fasteners.

Vacuum Environment Performance provides an inherently particle-free and non-magnetic thread solution, avoiding the need for secondary coatings or specialized finishes.

Vibration Loosening Protection dynamically absorbs continuous shock and impact forces to preserve joint integrity without adding bulky locking mechanisms.
