Yankee Screwdriver No. 31A Hex Torx Screwdriver Adapter
3Have a Yankee Spiral Ratchet Screwdriver? Need a hex/Allen/Torx head bit for it? This adapter is for standard Hex drive bits, giving you the ability to use hex head (short bits) like the ones in the include set. This adaptor is made in the USA and comes in three sizes on the Yankee connecting end, this one is .312 (5/16") diameter for the Yankee 31A, 131A and some other models by Yankee and other makers, like Millers Falls, and Greenlee, large size models as well. I also have a smallers shank size availiable at this website. On the hex end there is a coil spring the grasps the hex bit when it is inserted keeping it from falling out. (Don't use bits that are stepped down as they will become stuck in the adapter. Small knotches are fine, like the ones shown in the pictures. This set includes 7 different Torx sizes, (T-10 to T-45), and 6 different Allen Head or Hex head sizes (5/32" to 3/8"). A real nice addition to your bits for a Yankee screwdriver! <br> Shipped in the contental U.S.A. is $3.00.
