Screw Tightening Torque - Toshiba TECRA A9 Series Maintenance Manual

4 Replacement Procedures

Screw Tightening Torque

When you fasten screws, be sure to follow the torque list below.
CAUTION: Overtightening can damage components and screws; undertightening can
result in electrical shorts or other damage if screws or components come
loose.
NOTE: Toshiba recommends that you use an electric screw driver for quick and easy
operations.
• M2
• M2.5
• M3
NOTE: To prevent damage to THIN HEAD screws, use type 0 bit philips screwdriver.
Use, however, the PH point size "1" screwdriver for screws fixing the memory
slot cover and keyboard. Press along the axis of the screwdriver while turning
the screw. This is because the contact area between the screw and driver is less
than for a pan head screw (standard pan-shaped screw head).
