The Far and Near crank arm bolt is designed to replace the non-drive side bolt on most Shimano Hollowtech II cranks. It also has a distinct advantage of being adjustable with a 5mm allen wrench not the proprietary Shimano tool allowing an easier install. Shimano does say that the reason they went to the hard to tighten hand tool for their two piece cranks was to prevent over tightening that will ruin cranks. Therefor the 3 Newton Meter torque rating should be strictly followed during install.
Most Shimano Hollowtech II designs, including all current road and mountain cranksets use the M20 x 8mm threading and are compatible with the Far and Near Crank Bolt. This bolt is not compatible with cranks using the M15 bolt such as Ultegra 6600 and 105 5600 use an m15 fixing bolt, and so are not compatible with this Far and Near bolt. XTR M970 cranksets are also incompatible.
