Hi, I thought I was drilling 1/2in but it was 9/16th... I was going to use wedge anchors but no amount of pounding will make them expand enough. Would strike anchors work? They appear to be in annoying sizes, and I'll need a few sizes I think so I'm not about to order a few hundred. But maybe someone carries them locally I don't know about? Well, or do lag bolts work?
It's just to hold two steps down that are for the patio door of the house.
