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: Our company recommends that you use an electric screwdriver for quick and
easy operations.
M1.2 (1.2mm) 0.0245 Nꞏm (0.25 kgfꞏcm)
M2 (2mm) 0.167 Nꞏm (1.7 kgfꞏcm)
M2.5 (2.5mm) 0.294 Nꞏm (3.0 kgfꞏcm)
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).
