wrt the torque adapter from HF, it is only an in-store purchase. Listed on website for about $25 -- cheap -- but no store near me has one. I found similar item by Delco (??) on Amazon, I think, many more $$ but looks like the real deal. Might be a handy tool. I have never sprung for one of those gazillion piece tool sets with every socket or wrench known to man. I Just buy what I need sorta when I need it. After about 50 years of that, I have a lot of tools, and you'd think I'd have all I need. But no . . . seems I'm always looking for one more this or that. In all that time I think I broke one 3/8 drive ratchet (it was seriously abused) and split out one spark plug socket. Along the way I came to really appreciate 6 point sockets vs the more ubiquitous 12 pt, and now have many of each.
