Can anyone you tell me where to find this type of self centering screw driver adapter that fits into a drill? It is spring loaded, so after you attache it to a standard screw, the sleeve will keep the bit from slipping off of the screw. I bought these years ago, can't remember where, and know one I've talked with here has any idea what I'm talking about. I can't seem to find them searching on the Internet. Probably because I don't know what to call it.
