To prevent splitting wood, in general, you can drill a pilot hole with a smaller diameter drill bit. That way there is a minimum of intrusion with the screws that close together. You would think that the particle board core wouldn't split but mine did when the second one was put in at the factory. Also the tapered bottom of the screw head will split the wood if it distorts the slot enough, from over torquing. The solution would be to replace the screws with flat bottom heads. I think that after I filled the holes with a wooden plug and glue it would not require a second screw.
