Caution
Use care when installing self-tapping screws in plastic. To properly start
the screw in plastic, turn the screw counter-clockwise in the hole until you
feel the screw engage the threads, then tighten as usual. Improperly
aligning or over tightening the screw can result in damage to previously
tapped threads.
Always use the correct type and size screw. Using the wrong screw can
damage tapped holes. Do not use excessive force to remove or install
either a screw or a printer part.
