Hand Installation Tools

Heli-Coil manufactures various designs of hand installation tools.

Generally, finer pitch inserts are proportionately larger in the free state than coarse pitch inserts and therfore have to be “pre-wound” to a smaller diameter for installation.

Large coarse pitch inserts (and 2-56, 3-48, and M2.2 inserts) need only a threaded mandrel tool for installation.
