We only use those for drywall.Through bolts are for much heavier loads. A 100# piece of equipment is nothing. If you have four bolts, that's 25# per bolt. (Although I always size it so that any one bolt could bear the whole load - anything worth building is worth overbuilding. But the 100# is in shear, not tension (not pulling out of the wall). The shear strength on say a 1/4" bolt is way over 100#. A single 1/4" toggler could handle the whole load.

I would not consider those unless we were sandwiching drywall, furring strips to the wall
