Drill your hole 1 size bigger than 1/8 which is 9/64 or screw will break off before it hits holder!
Works great the scores in the screws are perfect. I have a real hardwood floor tongue and groove and the 1/8 bit was too small i broke off 2 screws before they were all the way in so I had to remove them with vise gripe locked on the broken screw to remove it. I went and got 1 size bigger drill bit 9/64 and it worked perfectly! Good buy, great design. Pulled my hardwood down enough to subfloor to eliminate that little gap and to stop that squeak noise. Just go ahead and buy another box of screws you’ll need them!! Use your shavings from drill hole you pre drilled to put back in the hole I mixed my shaving with a bit of glue let it dry in hole then used a wood stain marker. Can’t even tell where I drilled hole they also sell a kit of wax for hardwood flooring holes fill hole with the color to match and run your little heater wax melter in kit across it to melt looks perfect!
