Product Description
The Heli-Coil® 1191-6EN375 is a tanged, free-running wire thread insert precision-manufactured from Nitronic 60 stainless steel. Engineered to establish high-strength, anti-galling 3/8-24 UNF fine internal threads in low-density parent metals such as aluminum and magnesium, this insert features a tanged design for reliable driving and insertion depth control. Its high-performance Nitronic 60 alloy composition provides exceptional galling resistance and wear protection without requiring secondary coatings or lubricants, allowing smooth thread engagement and long-term durability in high-cycle or high-stress structural joints.
Tanged Wire Construction provides a sturdy driving notch for controlled installation and precise positioning within tapped holes.
Nitronic 60 Stainless Steel offers superior resistance to galling, thread seizing, and wear under continuous high-load operations.
Free-Running Thread Profile allows standard male fasteners to pass through smoothly without applying friction locking torque.
3/8-24 UNF Fine Threading reinforces soft parent metals and repairs damaged fine internal threads in high-precision mechanical components.
1D Nominal Length Ratio delivers optimal load distribution and thread engagement in compact structural designs.
