Screws; Special Handling Of Components - HP Xw4600 - Workstation - 2 GB RAM Technical Reference Manual

Screws

The screws used in the workstation are not interchangeable. Metric screws are used for optical and
diskette devices, and American National Standards Institute (ANSI) screws are used for hard drives. If
an incorrect screw is used during the reassembly process, it can damage the workstation. HP strongly
recommends that you keep all screws removed during disassembly with the removed part, and then
returned to their proper locations.
NOTE: Metric screws have a black finish. ANSI (unified) screws have a silver finish.
As each subassembly is removed from the workstation, place the subassembly away from the work
area to prevent damage.
Additional drive-guide screws are provided on the system chassis in case they are needed. The
Figure 5-1 Metric and ANSI screw identification on page 55
located on the chassis near the 5.25-inch optical drive bays. These screws can be used to mount
additional optical drives or an optional diskette drive. There are four ANSI 6–32 screws (2) located on
the chassis near the hard drive. These screws can be used to mount additional hard drives in the 3.5
inch hard drive cage.
NOTE: The metric (black) and ANSI (silver) screws are not interchangeable.
