Heli-coil 17551-3 Thread Insert Tool 10-24 Unc Crank

Product Description

The HELI-COIL 17551-3 is a crank-style hand installation tool designed for driving tangless thread inserts into pre-tapped holes. It is built for 10-24 UNC thread inserts and delivers controlled, manual installation without the need for pneumatic or electric equipment. The crank handle provides steady torque feedback, allowing technicians to seat inserts accurately in metal, plastic, or composite substrates. Weighing 0.3 pounds, it is a lightweight bench or field tool suited for machine shops, production assembly, and maintenance operations. HVAC, electrical, and mechanical service technicians use this tool when repairing stripped threads or installing insert-reinforced fastener points during equipment servicing.

This tool is intended for hand installation of tangless thread inserts in 10-24 UNC tapped holes. It is well suited for light industrial and maintenance applications where threaded insert repair or reinforcement is performed on aluminum housings, sheet metal assemblies, and cast components. The crank style is preferred in situations requiring fine control over insert depth and seating, particularly in confined areas where powered drivers are not practical.

Installation Notes

This tool is installed and operated by machinists, maintenance technicians, and assembly professionals.
