Review on SK Hand Tool 40015 Socket by Sam Duppa

Great Allen key. Fit and finish are first class. The six-point cutout is partially recessed to accommodate the object you are working on, followed by a narrower circular indentation. This provides a stronger head and a more precise fit than a standard 12 point head that is fully countersunk top to bottom. The embossing on the bottom is good, the size and part number are easy to read. The exterior finish is polished chrome, although I had to use light steel wool to remove some of the plating left over from the finishing process. I also bought a small set of 15 items from SK.
