Bests & Worsts Reviews from Amazon

I found out about this tool when shopping for a new disposal. I knew it was simply an allen wrench, so I searched online to find what size would work. I couldn't find the info anywhere, so I'm posting it here. This is the same as a 1/4" allen wrench. If you already have allen wrenches, no need to buy this one. If you don't, spend the six bucks on a nice balldriver allen wrench set that you can use for other jobs.
