These screws should work well for various projects requiring a slightly shorter screw; I bought the 2 and 1/2 size too, and will work well with the Kreg jig I bought and the driver bits, or could be used by themselves for standard screw, i.e., non pocket hole screws.  It helps to have the Kreg driver bits that fit the square top (as a straight or Phillips won't work).  Seem sturdy and ought to have plenty as I bought about 100 or better (see pack size).
