What size hexagonal keys fits the truss rod and bridge adjusters?

The main reason these adjusters get damaged is that they are (generally) imperial sizes, which are getting more difficult to get keys for. The truss rod uses a 5/32″ key (approx. 4mm) while the bridge adjusters use a 0.050″ (1.27mm) key. The 5/32″ should be easy enough to get from car or bicycle spares shops, but the 0.050″ keys are very difficult to get, and usually have to be bought in multiple packs. The Homepage can supply 0.050″ keys individually for £2.50 including UK postage.
