Just realise that the Strat I am getting tomorrow I will need to do a quick set up and being a used Strat (MIM Road Worn), it doesn't come with the little allen key to adjust the bridge.  (seller confirmed no case candy)

Will this work?

Allen keys 1.5mm, 2.5mm, 3 & 4, 0.05", 1/8",3/16".

Can someone tell me what size allen key is that and where I can get it?  While I am at it, I might as well get a steel ruler and perhaps a radius checker thing?

Pretty sure my both my USA and Mexican Fenders take a 0.05 in Allen key for the height adjustment screws.
