Heli-coil 7571-2-5 Thread Insert Tool Replacement Blades 8-32

Product Description

The HELI-COIL 7571-2-5 is a replacement blade set for hand installation tools used with tangless thread inserts in 8-32 UNC applications. These stainless steel blades fit into compatible HELI-COIL hand installation handles and provide the driving engagement needed to install tangless coil inserts without leaving a tang that requires removal. Replacement blades extend the service life of existing installation tool handles, keeping repair and re-threading operations running without requiring a full tool replacement. Licensed HVAC technicians, maintenance mechanics, and precision assemblers working on threaded repair applications rely on these blades for consistent, accurate insert installation.

These replacement blades are intended for use in hand-operated tangless insert installation tools servicing 8-32 UNC threaded holes. Common applications include thread repair on aluminum housings, sheet metal assemblies, and other components where standard UNC threads have been stripped or damaged. The 8-32 thread size is frequently encountered in control panels, electrical enclosures, and light mechanical assemblies across residential and commercial service work.
