TonyJZX,

The Dell part number for that screw is 6350E.  It may be available only as part of a screw kit (bag of screws).  Dell's spare parts number is 1-800-372-3355.  If you have difficulty purchasing this item from Dell, you can purchase it from an aftermarket supplier such as Impact Computers.  Check this link:

This one holds in the HDD bezel. According to the service manual it's a M3 x 5mm. Where can you get these? Doesn't seem to be a standard size.
