    After failing to find a torque screwdriver and bit that would allow for easy use of the adapter I finally found the perfect bit to work with the relatively inexpensive wrench I bought at Home Depot. The issue is standard bits aren't deep enough to access the screws. The B4 mount is slightly easier than the PL mount but both are very tricky with a standard bit and any torque screwdriver I can find.

    You must use the proper torque wrench set to the specified torque 0.45 Nm for the PL/B4 mount... I found a Wera 7440 ESD 0.3-1.2 Nm torque driver at OpenTip in the US of all places! There's nothing like it anywhere near the price in Canada and I tried for hours to find it online here or in the local stores.

    The proper bits aren't easy to source either. I managed to find a set at a local hobby store thank goodness after searching all hardware stores and coming up empty.

    In those areas burdened by the "traditional systems of weights and measures" 0.45 Nm is 3.9828355953209997 lb-in. Which is in the range of the Husky I listed. Also be advised if you go asking for a torque wrench instead of a torque screwdriver you will get erroneous results.

    Tell me about it. I went all over. These longer bits were a true find. Thus sharing with the community.

    I'll post a photo of my hex bits. They're available from distributors in Germany and Shanghiai, made in Taiwan. Dynamite from Dynamiterc.com so that might help you find them.
