Screws
The screws used in the workstation are not interchangeable. They might have standard or metric threads
and might be of different lengths. If an incorrect screw is used during the reassembly process, it can
damage the unit. HP strongly recommends that all screws removed during disassembly be kept with
the removed part, and then returned to their proper locations.
NOTE Metric screws have a black finish. American National (unified) screws have a silver finish.
NOTE As each subassembly is removed from the workstation, place the subassembly away
from the work area to prevent damage.
