You can't, they have to be very light and flexible.
They're lightly twisted together for best possible hum cancelling anyway.
You can't use screened wire in the pickup arm for the simple reason that it's not flexible enough and will cause the tone arm to put more stress on the groove walls of the record causing mistracking and damage.
In high impedance circuits with crystal cartridges, the stray capacitance in screened cable causes attenuation of the high frequencies making the player sound dull, which is another reason not to use it and keep any that is used to a minimum length.
It could possibly be that your cartridge is slightly low on output and you're more aware of any residual hum at the particular volume setting.
Don't try getting switch cleaner into the pot via the shaft - squirt it in via the connecting tags if you can.
