I recently purchased a few new sets of SK SAE 12-point sockets in various lengths and drives for an aviation maintenance tool box. All of the sockets 5/16 and below were extremely rough on the inside, so much so that they didn't fit properly on 12-point nuts. Is this a normal thing for new Sk sockets, or did I draw the short straw and end up with four separate sets of pre-Ideal stock? I sent an e-mail to SK asking about warranty, but only received a response that they would forward it to the quality department and nothing since.
The attached pictures are of the 3/8 Drive 1/4 socket. I wiped the gray corrosion preventative coating off from this socket, so I'm assuming the bits sticking up are either metal from the manufacturing process or flaking chrome.
