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 (2mm) 0.167 N·m (1.7 kgf·cm)
• M2.5 (2.5mm) 0.294 N·m (3.0 kgf·cm)
• M3 (3mm) 0.549 N·m (5.6 kgf·cm)
NOTE: To prevent damage to THIN HEAD screws, use type 0 bit philips screwdriver.
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).
