Listing details

Vtg Cornwell USA D-314-3, 7/16" Hex-Drive Impact to 1/2" pinned socket adapter.Excellent, near new condition. Most appear never to have been used.Note: The drive

size is 7/16" measured 'across the flats' of the head; which is to say a 6-point 7/16" socket fits it. I'm not sure if this translates directly to the

size of the drive chuck (like, is the chuck

size a 3/8" even though it fits a 7/16" shank?). If anyone can tell me, it would be appreciated so I can update my listing. Please see pics and check my feedback; I ship promptly and insured. Shipping is a flat fee to the CONUS; Alaska, Hawaii, and international shipping is available, but will be at an additional cost to be invoiced to the buyer following the sale.
