Not spanners but screwdrivers.
Over the years I’ve come to hate Phillips (PH) cross head screws, a minor amount of corrosion and cheese based alloys the heads strip before the screw moves. The great secret is that they were designed to do that, the shape of the tip was/is designed to cam out under torque - pity no one owned up to it.
Pozidrive (PZ) screws and their screwdrivers (identifiable by the secondary cross on the screw head or fluting on the screwdriver) were designed not to cam out but are not interchangeable and will just make matters worse.
The Japanese in their wisdom use a form akin to Philips that does not ride out but also decided to keep it secret. JIS screwdrivers will interchange with Philips fixings and work better than PH drivers. (Mind you, a PH screwdriver will still wreck a JIS fixing, just look at the crankcase on older Japanese bikes)
A bit of digging on the ‘net will throw up JIS screwdrivers, they work, they grip and they don’t cam out. Vessel manufacture a quality range, which I can recommend, including an impact version.
If you have a Japanese bike or car, the ‘cheapo’ dual pointed screwdriver in the tool kit is probably JIS and will probably be better fit than any quality make with a PH head.
At one time JIS heads had a single dot punching on the head to identify them as such, though this I understand is no longer a requirement of the standard.
