First put the screw through a flathead washer (if you are using one) and insert it through the protective guard you want to attach. Then put the Savetix® washer onto the screw from behind and screw the protective guard into position on the housing or frame.
The Savetix® washer gets flattened during this process, making the hole smaller than the diameter of the threaded part of the thin-shank screw.
This deformation means that Savetix® has reduced the inner radius of the screw-hole so that the threaded part of the screw cannot fit back through the hole in the Savetix® washer or the protective guard.

Proper installation:
The bore of the mating thread corresponds to the diameter of the hole Savetix disc.
Incorrect installation:
The bore of the counter-thread is larger than the diameter of the hole Savetix disc.
Ideal mounting case:
Special case, when the screw is very small:
Important: In this variation, the through-hole in the inspection cover must correspond to the diameter of the hole Savetix disc:
M4 = 4,1 mm, M5 = 5,1 mm, etc.
Possible error with thin screws:
Flanged wheel, possibly tears off the head of the screw!
