my 5mm allen wrench doesnt reach and the tool in my tool bag seems to be missing a piece bc it doesnt fit, can you tell me exactly what tool you used?

I used a standard 5mm allen wrench, however the wrench I used was double-ended and I did have to use the long end because the short end would not reach. I recently bought a whole set of standard metric allen wrenches for $9 at a generic auto supply store.
