Koken Whitworth sockets
These 3/8" drive 6 point socket sets include the most commonly used sizes on a British motorcycle engine. Don't buy crap from China or overpriced vintage Snap On when these beautifully made sockets are readily available. Sizes include 1/8W, 3/16W, 1/4W, 5/16W, 3/8W, 7/16W, and 1/2W for the 7pc set, and the 8 pc set includes all the same and also the larger 9/16W socket. Both sets include a socket rail, and all sockets are marked in both Whitworth (W) and British Standard (BS)!
These high quality tools were made in Japan.
