Product Description
The Heli-Coil® 1185-8CN500 is a tanged, free-running wire thread insert precision-manufactured from 304 stainless steel. Designed to establish permanent, high-strength 1/2-13 UNC coarse internal threads in low-density parent metals such as aluminum and magnesium alloys, this insert provides outstanding corrosion resistance and long-term wear protection. Featuring a tanged design for controlled driving and precise depth control during assembly, its free-running thread profile allows standard male fasteners to pass through smoothly without applying friction locking torque.
Tanged Wire Construction provides a sturdy driving notch for controlled installation and precise positioning within tapped holes.
304 Stainless Steel Material delivers superior tensile strength, wear resistance, and reliable protection against corrosion in structural applications.
Free-Running Thread Profile permits standard male fasteners to thread smoothly through the coil without friction locking torque.
1/2-13 UNC Coarse Threading reinforces soft parent materials and protects structural tapped holes against thread stripping and wear.
1D Nominal Length Ratio optimizes thread engagement depth and load distribution in compact, space-constrained assemblies.
