I was using an allen wrench of unknown size that was working great and it just stopped working. Be sure you're using a new wrench that still has some bite. The cheap set I bought at walmart was only like 88 cents.
it is a 1/16 in they do make a "high torque" allen wrench that seems to be working a little better than the standard ones. Like Rita said I had been wearing the littl ebuggers out at a very quick pace and these new ones seem to be holding up much better.
