Apropos of the thread on nails vs screws, I thought I'd mention this. In both fine and coarse threads. Most people aren't aware of this, because 1 in 100 suppliers carry these.
The 3/4" really come in handy, so's they won't poke through countertops, etc. You might have to beg and grovel to get your supplier to order a box of each, but they will sell. Proly can find them online, as well, and mebbe even some other odd lengths.
