3585-06CN345 - Helicoil ® Threaded Insert by Stanley ® Engineered Fastening

The Heli-Coil® 3585-06CN345 is a tangless, screw-locking wire thread insert precision-manufactured from 304 stainless steel. Engineered to create permanent, high-strength .138-32 (#6-32) UNC internal threads in low-density parent metals like aluminum and magnesium, its tangless design completely eliminates tang break-off and retrieval steps, streamlining assembly workflows while preventing foreign object debris (FOD) hazards in sensitive electronics and aerospace components. Built-in resilient locking coils exert constant radial pressure on the male fastener to resist rotational loosening caused by severe shock and vibration without requiring external locking hardware.

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 internal locking coils that securely grip bolts to prevent vibration-induced loosening without needing lock washers or safety wire.

304 Stainless Steel Material delivers high tensile strength, structural integrity, and long-lasting protection against corrosion in precision assemblies.

.138-32 (#6-32) UNC Coarse Threading reinforces soft parent metals and protects miniature tapped holes against thread stripping and galling under load.

2.5D Nominal Length Ratio maximizes engagement depth to deliver exceptional pull-out strength in lightweight housing materials.
