Agree with david, every six months should be plenty. Every six weeks is too much, even with a torque ratchet you could easily overstrip the threads on the hex bolts. Think the bolts are engineer threaded not self tapping and screw into a metal threaded cavity that is punched into the mdf enclosure. Wood screws screwed straight into mdf are fine if they are never touched, but constant tightening would eventually make them loose their grip.
