Alpha ADP14-75SS 1/4" hex x 1/4" sq 75mm ThunderZone Impact Adaptor

The Alpha ADP14-75SS is a ThunderZone impact adaptor with a 1/4" hex shank and a 1/4" square drive, 75mm overall length (manufacturer-stated).

It lets an impact driver or drill that takes 1/4" hex bits run 1/4" square drive sockets. Alpha lists it in the ThunderZone range, whose text describes a patented spiral impact zone that distributes torque evenly, a compression forged tip, full body hardness and S2 raw material.

Alpha's product page states that this product has been superseded by ADP14-65SS, and the ThunderMAX range has its own 1/4" square adaptor at 65mm, linked below.
