Product Description
The HELI-COIL T1191-3E285 is a high-performance free-running tangless wire thread insert engineered to create strong, wear-resistant internal threads in soft metal base materials. Precision-wound from Nitronic 60 stainless steel, this #10-32 UNF thread insert features a 1.5D nominal length with a plain finish, combining a tangless construction with superior anti-galling properties to streamline assembly and safeguard critical components against high-friction wear.
Tangless Design eliminates drive tangs completely, removing the risk of foreign object damage (FOD) and saving assembly time by avoiding tang break-off and retrieval steps.
Nitronic 60 Stainless Steel offers exceptional resistance to galling, wear, and high operating temperatures without requiring additional anti-seize lubricants.
Free-Running Designallows smooth, unhindered bolt threading while distributing static and dynamic loads evenly across all engaged threads.
Bi-Directional Insertion features driving notches on both ends to enable fast, non-oriented installation using standard tangless power or hand insertion tools.
1.5D Nominal Length delivers optimal thread engagement depth to maximize pull-out resistance and overall joint shear strength in lightweight alloys.
