torque wrench adaptor for cylinder base nuts

I want to use a torque wrench to tighten the cylinder base nuts on my KDX 200 H series. I could probably do it with an open end crowfoot but don't want to risk rounding off the corners of the nut. It seems to me what is needed is a 12mm 12 point box end crowfoot wrench. I tried a 12mm flare nut crow foot but there's not enough clearance and it won't fit. Does anybody know if a 12mm box end crowfoot is even available? I couldn't find any. How do "those that know" use a torque wrench on these nuts?

I bought a MAC 12 pt adapter for a lot more money... :? But that is just what you need. Keep in mind that you will need to adjust the torque setting of the torque wrench to accommodate for the added length.

The little motion pro tool comes with a conversion chart.

I should probably get one of those. I've always just used a wrench with my calibrated human arm :cool: They need to be tight, and the same more than being a specific value....Never had a problem.

a simpler way to torque it without using the formula is to turn the adapter perpendicular to the torque wrench and use the specified torque value. this puts the box-end or crows-foot part of the adapter in the same plane as the dive of the torque wrench . it's an acceptable industry practise in aviation maintenance.
