1084-4CN060 - Helicoil ® Threaded Insert by Stanley ® Engineered Fastening

The Heli-Coil 1084-4CN060 by Stanley Engineered Fastening is a high-performance tanged free-running insert optimized for reinforcing or restoring fine internal threads in low-strength parent materials like aluminum and magnesium. Cold-rolled from precision Nitronic 60 stainless steel wire with a diamond-shaped cross-section, this wire thread insert automatically expands outward upon installation to establish a secure, spring-like retention force without the need for staking, keying, or swaging. The specialized material composition eliminates the need for additional anti-seize lubricants, effectively preventing galling and thread binding during joint assembly to deliver a permanently wear-resistant thread that shields critical structural connections from erosion.

Free-Running Profile Provides a completely smooth, conventional internal thread track that allows mating bolts to rotate unhindered without added locking friction.

Nitronic 60 Composition Offers superior anti-galling performance and wear resistance, completely eliminating the need for additional lubrication when using stainless steel screws.

Tanged Configuration Features a traditional driven installation tang that provides clean mechanical engagement with standard mandrels for accurate depth control.

Flexible Coil Structure Adjusts elastically to material expansion and contraction, minimizing localized stress concentrations to increase the fatigue life of parent materials.
