Is 2.5mm the right size for my Shimano brake levers?

Yes — most Shimano road brake levers (STI and flat-bar levers) use a 2.5mm hex bolt for the handlebar clamp. Verify by checking your lever's service manual.

Can I use the ball-point tip to torque a bolt to full spec?

No — use the ball-point only for initial positioning and light driving. Finish tightening to torque spec straight-on to avoid stripping the hex recess.
