Fit properly and made from decent steel so it held the full 18 inch lbs needed by the torque handle. I bought this to replace junk sold by Ama-you-know-who.

Nice
Out with the old, in with the new. I liked how WIHA performed in Project Farm’s testing so I decided to go with this brand, the good selection was a big factor. Others scored well but I didn’t just want a 5 piece set, I want them all ;)

I mentioned this adaptor in another review concerning the hex bits I bought. This adaptor allows me to make more use of my new powered screwdriver and 1/4" socket set. It's very well-made, affordable and has been a great addition to my kit.
