Product Description
The HELI-COIL T1084-4E060 is a high-performance screw-locking tangless wire thread insert designed to create high-strength, vibration-resistant internal threads in parent materials. Precision-wound from 304 stainless steel, this 1/4-28 UNF thread insert features a 1.5D nominal length with a plain finish, combining an exclusive locking coil mechanism that secures mating bolts with a tangless construction that completely eliminates drive tang break-off and retrieval steps.
Screw-Locking Mechanism utilizes a series of resilient locking chords on the central coils that exert strong radial pressure on the mating bolt, preventing rotational loosening under severe vibration.
Tangless Design completely eliminates drive tangs, removing foreign object damage (FOD) risks and reducing assembly time by eliminating tang removal and retrieval steps.
304 Stainless Steel Construction provides exceptional corrosion resistance, structural strength, and heat tolerance across demanding industrial and aerospace environments.
Bi-Directional Insertion features driving notches on both ends, enabling fast, non-oriented installation with standardized tangless power or hand tooling
1.5D Nominal Length provides robust thread engagement to optimize load distribution and pull-out resistance in low-shear materials.
