Where torque application accuracy is critical these tools meet the requirement. They offer excellent rigidity and surpass other wrenches in overall quality and efficiency. Wrench Type A is for sizes 1/2", 9/16" and 5/8" hex nuts. |
Ditto on grinding the o.d. and thickness of the nut end of the wrench but fine otherwise.
I had to grind the business end down considerably to fit the cylinder base nuts on my O-200, but apparently thats normal for any cylinder base nut wrench. Otherwise, fine.
The wrench will not fit my io520 with out a lot of grinding and they may still not fit.
