may differ slightly from this illustration due to variations in manufacturing
techniques).
Allen UNC Screws
Allen 4-40 UNC thread screws are used in some locations in the TM8000
radio and cannot be interchanged with M3 screws.
Pozidriv and Philips Screws
Both Pozidriv and Philips head screws are used on certain TM8000
accessories. It is important that you use the correct type and size screwdriver
to avoid damaging screw heads.
It is particularly important that you do not use Philips screwdrivers on
Pozidriv screw heads as the tapered driving flutes of the Philips screwdriver
do not engage correctly with the parallel-sided slots in the Pozidriv screw
head. This can result in considerable damage to the screw head if the
screwdriver tip turns inside the recess.
Note If you find you need excessive downwards pressure to keep the
screwdriver tip in the Pozidriv screw head, you are probably using
the wrong type or size screwdriver.
Figure 1.3 on the following page shows the main differences between typical
Pozidriv and Philips screw heads and screwdriver tips (actual hardware may
differ slightly from these illustrations due to variations in manufacturing
techniques).
