need a larger pilot hole because the wood is denser (harder). It’s always advisable to back out and re- drill a larger pilot hole if the screw gets too tight rather than risk breaking a screw.

Wood Screws: Performance & Mechanical Specs; Description. A thread forming screw having a gimlet point, and a sharp crested, coarse pitch thread. They are either produced with cut thread screws, which have a tapered shank, or rolled thread screws, which have a constant shank diameter.
The most common wood screws are number 6, 8, and 10, the larger the number the bigger the thickness. I almost always use #8 diameter screws. Longer screws are usually #10s. Common wood screw diameters. In the U.S. threads are sometimes indicated in threads per inch, usually 24 or 32 tpi.
