Both, the system of units as well as the size of threaded hole and male stud (e.g.
plug screw) must match.
Since the systems cannot be distinguished visually, there is a risk of mixing up.
WARNING
! Wrong threaded plug!
Risk of serious injury, if a male stud is used that differs from the threaded hole in
terms of unit system and size and is pressurized. The male stud may loosen itself
or even be ejected from the hole in a projectile-like manner.
Hydraulic fluid can be discharged from this leakage point.
▶ Use the drawings (installation drawing/data sheet) to determine the required
threaded plug for each fitting.
▶ Make certain that there are no mix-ups when assembling valves, mounting
screws and plug screws.
▶ For all threaded holes, use a male stud from the same system of units and of
the correct size.
