T3585-2CPF246 - Screw Threaded Insert by Helicoil Stanley Engineered Fastening

The Heli-Coil® T3585-2CPF246 is a tangless, screw-locking wire thread insert precision-formed from 304 stainless steel with a Primer Free II coating. Engineered to create permanent, high-strength #8-32 UNC threads in soft metals such as aluminum and magnesium, its tangless design eliminates tang break-off and retrieval steps, accelerating installation and preventing foreign object debris (FOD). Internal resilient locking coils apply uniform radial pressure on the mating fastener to resist rotational loosening caused by severe shock and vibration, while the specialized Primer Free II finish reduces insertion torque without additional liquid primers.

Tangless Wire Construction eliminates tang break-off and vacuum retrieval, shortening production cycles and 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.

304 Stainless Steel Material provides outstanding tensile strength, wear resistance, and long-term protection against corrosion.

Primer Free II Coating lowers installation torque and protects against galling without requiring secondary liquid primers or lubricants.

#8-32 UNC Coarse Threading reinforces soft parent materials and delivers durable, wear-resistant internal threads for critical assemblies.
