Before I strip the hex bolts, it's worth asking the question: Are the front wheel interchangeable with one another? Are the hubs threaded both left and right handed? I feel that my left wheel is not tightened adequately. It appears that I will need a torque wrench to tighten it. So here is the overall question: Is it "Lefty-loosy and Righty-tighty"; or the inverse?
Please forgive me if the answer is obvious.
