Heli-coil 3747-14 Thread Insert Tool M14 X 2.00

Product Description

The HELI-COIL 3747-14 is a hand installation tool designed for driving threaded wire inserts into pre-tapped holes. It accepts M14 x 2.00 metric coarse inserts and delivers the controlled torque needed to seat each insert flush and true without damaging the surrounding bore. The tool is used by mechanics, machinists, and maintenance technicians working on thread repair and thread reinforcement applications in metal components. It is the correct driver for HELI-COIL inserts in the M14 x 2.00 metric coarse thread standard.

This tool is suited for bench work and field repair where power installation equipment is not practical or required. It is commonly used in automotive, industrial, and general metalworking environments when restoring stripped or damaged threads to full load-bearing capacity. Hand installation tools of this type are appropriate for low-volume insert work, prototype builds, and service applications where one or a few inserts are installed per job.
