Heli-coil T1185-2C328S Free Running Insert 8-32 Ss 1000pk

Product Description

The HELI-COIL T1185-2C328S is a tangless, free-running wire thread insert designed to create strong, wear-resistant internal threads in parent materials that cannot support reliable threading on their own. Built from 304 stainless steel, this insert measures 0.328 inches overall length and is sized for 8-32 UNC thread applications. The 2D length-to-diameter ratio and 8-3/8 free coils provide solid thread engagement. The tangless design eliminates the need for tang break-off after installation, reducing installation time and eliminating the risk of metal fragments in assemblies. This insert is supplied in a pack of 1000 units, making it suited for production or high-volume repair environments.

Free-running inserts in the 8-32 size are commonly used in precision assemblies across HVAC equipment manufacturing, electrical enclosure fabrication, and mechanical equipment maintenance. They are installed in aluminum, magnesium, cast iron, plastics, and other materials where thread strength needs to be brought up to standard or restored after damage. Maintenance technicians, assembly line workers, and field service professionals across the trades use these inserts to restore stripped or damaged threads without replacing the parent component.

Key Features

• Tangless design - no tang break-off step required, reducing installation steps and debris risk
• 304 stainless steel construction for corrosion resistance in demanding environments
• 8-32 UNC thread size, 2D length-to-diameter ratio for reliable thread engagement
• 0.328 inches overall length with 8-3/8 free coils
• Pack of 1000 inserts for production or high-volume service use

Compatibility

Designed as an OEM-style replacement or new-installation thread insert for any application requiring 8-32 UNC internal threads in aluminum, soft metals, plastics, or other materials where direct threading is insufficient.

Installation Notes

Installation requires a HELI-COIL or compatible tangless insert installation tool and a properly sized STI (Screw Thread Insert) tap for 8-32 threads. Always tap the parent material to the correct STI thread form before inserting. De-energize any equipment and follow applicable safety lockout procedures before performing thread repair on installed assemblies. Tangless inserts do not require a tang removal step, but verify final thread engagement with a go/no-go gauge where tolerances are critical.
