Lee Valley published a report years ago on the superior holding power of 
machine screws over wood screws. I have followed their advice with good 
results, using ordinary metal taps and bottoming taps in oak, for 
example. This was particularly useful in securing hardware to 3/4in 
rails on a bedframe, where there was not much thickness for purchase, 
and I didn't have to worry about the points peeking through!
