2.1 Torx Recess Head Screws
Torx recess head screws are becoming the standard screw head type in all T800 SL2
equipment, with Pozidriv and Philips recess head screws being used in fewer applica-
tions.
The Torx recess head has the advantage of improved screwdriver tip location, reducing
the chances of screw head damage caused by the driver tip rotating within the recess. In
addition, using a ball-tip Torx screwdriver allows you to drive a Torx head screw with
the driver on a slight angle, which can be useful in situations where access is restricted.
It is important that you use the correct Torx screwdriver tip:
M3 screws T10
M4 screws T20
Figure 2.1 below shows a typical Torx recess head screw (actual hardware may differ
slightly from this illustration due to variations in manufacturing techniques).
