3585-8CN1000 - Helicoil ® Threaded Insert by Stanley ® Engineered Fastening

The Heli-Coil® 3585-8CN1000 is a tangless, screw-locking wire thread insert precision-manufactured from 304 stainless steel. Engineered to establish permanent, high-strength 1/2-13 UNC internal threads in low-density parent materials like aluminum and magnesium, its tangless design completely eliminates tang break-off and retrieval steps, streamlining heavy-duty assembly and preventing foreign object debris (FOD) risks. Built-in resilient locking coils exert uniform radial pressure on the mating fastener to resist rotational loosening caused by severe shock and vibration, eliminating the need for external locking devices.

Tangless Wire Construction eliminates tang removal and vacuum retrieval steps, shortening assembly cycles and completely preventing foreign object debris (FOD) hazards.

Screw-Locking Mechanism features straight-segment internal coils that securely grip bolts to prevent vibration-induced loosening without needing lock washers or safety wire.

304 Stainless Steel Material delivers exceptional tensile strength, wear resistance, and long-lasting protection against corrosion in structural joints.

1/2-13 UNC Coarse Threading reinforces soft parent metals and protects tapped holes against thread stripping and galling under heavy load.

2D Nominal Length Ratio maximizes engagement depth to deliver exceptional pull-out strength in structural components.
