Good Spare To Carry On A Long Tour

I recommend this product
ProsSmall, Light, Good Quality
I bought a couple as spares in case one ever fell out, or got damaged on rough and off road tours. I don't expect to loose one as I use Loctite, but if I do they are small enough and light enough to get you out of that situation in remoter areas. Not sure how long one grub screw would last in those condition but best to be safe!

Prossee above
Good choice of material and use both of hex head and slot for flexibility of tools. Successfully locks the eccentric. But I have lost two in two years!
I have two suggestions: (a) Thorn to consider the use of a locknut for each screw / alternatively recommend use of Loctite or similar. and (b) for one of the screws to be longer than the other, to make securing the second screw with a spanner the easier.
