Review on Collapsible Shelf Brackets - Heavy Duty Metal Folding Bracket For Wall Mounted Bench, Table, Or Shelf, Space Saving Hinge Design, 2 Pack, Maximum Load Capacity Of 150 Pounds (14 Inch, Black) by Adrian Woodside

The installation video suggest using an 8 MM (.315") drill bit for the anchors, I used a slightly smaller one (.3125"). However, after making all 3 holes for the first bracket, I noticed the anchors were way too small so sure enough they were completely loose in the holes. You may want to use a .25" drill, but honestly I would just buy anchors separately. Unfortunately now, I have to patch 3 holes on my wall.Another thing, the wood screws included for mounting the brackets to the tabletop are the cheapest I've seen: 2 of the 8 used broke at the head, so my tabletop is only being held by 6 crappy screws. I will replace these as well, except for the 2 screw bodies I can no longer pull out of the wood.
