A while ago I posted about swapping out some tools and had been thinking that I should probably just buy an 8mm 1/4" socket bit. But I haven't - and I had to take the topend apart to replace the rings on my 450 - and I do all of my maintenance with these tools - and I just couldn't put enough torque on that stubby little 8mm wrench. So I popped an 8mm socket on the end of it and whammo! Now I'm thinking that instead of buying a dedicated 8mm socket bit, I'm just going to cut off an inch long piece of an 8mm allen wrench and carry that. Way smaller/lighter than carrying a whole allen wrench, and even a little bit lighter than carrying a dedicated 1/4" 8mm bit.
