The screws and anchors in this set do not match. You will receive 100 #10 screws and 100 anchors that fit #8 screws. It also comes with a #10 masonry bit size for anchors. So if you use the included drill you will get a slightly larger hole and if you try to insert the included screws the dowel will push right through the hole. Wall. You could get away with this if you're actually screwing into masonry, but if you plan on using them for drywall, forget it. Not worth returning either, so I'm now buying 100 #8 screws and 100 #10 anchors to use this box of mismatched screws and anchors. The only reason I gave it two stars instead of one is that the screws and anchors are actually good quality. You just can't use them together.
