How much higher? You seem to imply that a 1/2" screw isn't long enough? The screw goes through the PC Board (~1/16"), a fiber washer (<1/16), a 1/8 standoff, a shoulder washer (<1/16), the transistor tab (<1/16), insulator and heatsink (~1/16); total ~3/8, leaving plenty of thread.
A "2D" fastener is about 1/4, which should be very close to the fiber washer (<1/16), a 1/8 standoff, shoulder washer (<1/16), the transistor tab (<1/16), and insulator.
