So my main issue was my fault, but there were also some flawed knobs that, even before i tried installing them, wouldn't allow the screw to be screwed in all the way. I only needed 6, though, so I had enough cleanly cut knobs to get the job done. Four stars for anyone who needs every knob in the pack.But a preventable cautionary tip, too:I might have payed more attention to the length of the screw, but I didn't and had to drill an additional larger hole exactly deep enough for the head of the screw to sit perfectly inside the cabinet at the right length. Ended up putting some super glue in the hole to hold the knob flush for those I drilled a little too deep.
