Application in sheet steel through-holes

Industrial fan

Screw fastening for fan modules into through-holes
in sheet steel using TAPTITE 2000® M5 I.

Secure screw fastenings into sheet steel

Low tapping torques and high tightening torques
and overturn torques ensure secure processing for
the screw fastening. A high level of component
security was achieved by using TAPTITE 2000®
strength class 10.9.
