Came across this yellow bolt recently...Don't see them very often and can't remember what they are called.
It's on a classic Spanish motor, anyone know it's proper name and who sells the tools for it.
I haven't got time to make a tool at the mo.
Cheers
It's an early 80s Suzuki Santana. In for a rewire and to sort the brakes.
Couldn't find pentagon socket set but only after a quick online search... Must try harder.
