Looking at the photo with some structural engineering skepticism, I'm 
inclined to say that to properly contain a 100 lb. radio through poor 
but expected handling, the fasteners should be about double the 
diameter shown, they should have large washers under the heads, and 
there should be at least 4x the number shown (better, 8-10x).  Also, 
what do the screws thread into?  Are they self-tapping screws or wood 
screws?  (No good, unless they go full-depth into a hardwood 
2x2.)  Tee nuts?  OK if there are plenty of fasteners.  Proper nuts 
with large washers?

Of course, there is a lot we can't see from the photo, so it could be 
better than I surmise -- but those are my observations from many 
years of experience crating heavy stuff for shipment.

Best regards,
