When I lost the 2 socket wrenches I used to tighten and loosen the bolts on my hitch mounted bike mount, I didn't want to pay $10-15 for a new regular one stores or spend money on a brand new set for just one outlet size. I found this for only $2 and it worked great. Fits well on my socket wrench, with strong grooves. Couldn't have asked for a better replacement and the price was literally unbeatable.
