Be careful when adapting to a smaller drive. As the power input may be too high for the smaller drive square, there is no guarantee when adapting down. The standard external square of Momento’s 1/4”, 3/8”, 1/2” and 5/8” adapters has a plunger retainer. All larger external squares have a through pinhole.
With Momento’s compact insert adapters to a smaller drive square the overall height is reduced to an absolute minimum. Momento’s insert adapters are specially designed for use with impact sockets. Having the normal female square of a power adapter they are stronger than open insert adapters with a square through hole. The insert adapter sticks to the socket by means of a magnet.
