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 screwdriver 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).
