How tight should chainring bolts be?
A Shimano “General Operations” manual states the tightening torque for road chainwheels is 12-14 N-m. For mountain bike chainwheels it’s upped to 14-16 N-m for large and middle ring and 16-17 N-m for the smallest ring of a triple.
Can you reuse chainring bolts?
Chainring bolts made of Steel or Titanium will typically last longer and can be re-used more times than aluminum bolts. … If the bolts look good and function smoothly, there is usually no reason to replace them.

What are crank bolts?
Crank bolts, as the name suggests, are used to secure the crank to the axle (spindle) of the bottom bracket(BB). While they are another of those parts that may go largely unnoticed by most riders – sometimes they are even covered by a dust cap – they may become loose and worn over time and require replacement.
