...and get some JIS screwdrivers.
If youve not heard of it before (dont worry, I hadnt until recently), JIS stands for "Japanese Industrial Standard", which has been around since 1916. JIS crosspoint screws are very similar to the phillips standard, but arent the same, and are still being used on Japanese bikes, as well as a lot of European ones.
The phillips standard was created in 1936, based on the JIS crosspoint, but designed to 'cam out' before maximum torque was reached. It was primarily meant to be used on assembly lines, where a broken or stuck fastener could mean stopping the line to repair, and at a time when metallurgy was nowhere near the level it is at today, so broken fasteners were much more common.
This perfectly explains why its so hard to unstick a screw with a phillips screwdriver, and one often has to resort to an impact driver. They just arent designed to transmit that much torque.
JIS screwdrivers fit the screw head much better than a phillips (and not just JIS screws, Ive found they work better on standard phillips screws as well). They are designed to let the user transmit as little or as much torque as they want to, without camming out. And I can speak from personal experience, they do just that.
This vid (while a little long and a bit boring) perfectly demonstrates this:

I bought #1-3 sizes of the Vessel brand, and my high dollar Matcos now mostly collect dust. I ordered from RJRCOOLTOOLS
but RRR Tool Solutions
has more complete sets.
