I used an inch pound torque wrench.. I try to always use torque wrenches if a spec is given (I have over tightening syndrome
)
Anyway, going to Home Depot and Lowes was an exercise in "are you F**k'n kidding me"!! Lowes didn't have the bolt in stainless, and Home Depot had stainless bolts but not in metric!!!
It's a M5 x .08 x 16mm stainless steel flat head allen bolt. I think that .08 should read .8 (obviously wouldn't be the first typo in these instructions)
