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. Hewlett-Packard 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 Standards Institute (ANSI) screws have
a silver finish.
