So this is a technique that I use whenever I come across a hole that needs filling because the screw within it for one reason or another has stripped it out and it no longer fastens it's intended work piece to the substrate. It's quick. It's easy. It's even kinda fun. Best of all, you don't have to waste any money on garbage anchors from the hardware store because this method, hands down, beats the pants off and spanks those silly little anchors. This also works great on transition strips between flooring surfaces such as lino to carpet when installed over concrete slab foundations if you first drill your pilot hole with a masonry bit.
