I need a 3/8 and 7/16 long wrench to work on aircraft engines, they are great for that as do all other gearwrenches -Products are top-notch in fit and finish, and the thin side of the box wrench tool allows me to access hard-to-reach places. I looked at the Snap-on brand keys and was able to purchase the whole set for the same price as two truck keys and am happy with the purchase.
