2.1 INTENT OF USE
The 74290 Tool is designed to convert round holes in to hexagonal holes. The latter are produced by means of a drill. Then
the tool, equipped with punch and reference die, is to be inserted into the hole, where it removes other material in order to
obtain a hexagon hole, ready to receive threaded hexserts.
In this way it is possible to easily and rapidly install threaded inserts which, owing to the hexagon profile, guarantee the on-
rotation of the joint, with evident advantages regarding the production process and the offered performances, compared to
round threaded inserts or other competitor technologies (nuts, welded nuts, etc...).
The use of this tool for threaded inserts enlarges the range of application (up to now it was restricted to the employment of
pre punched sheets) for box type design pieces, low volume series production and in situ applications.
For further details regarding the preparation of the hole in relation to the type of material and the thickness, see page 12.
DO NOT use under wet conditions or in the presence of flammable liquids or gases.
