Said this in the past and state it again now.
You never have to back limb bolts off of a modern compound bow during the off season.
They (limbs) are rated from 130,000 psi to over 200,000psi
They will never be damaged from leaving them strung the way they came.
Shooting too light of an arrow, dry firing, and leaving your bow in extreme heat are the main reasons they are damaged.
Leave the limb bolts alone unless you need to take your bow apart to inspect it after a dry fire.
