Pro-Twist CS1005 5-lb Pack Bugle Coarse Sharp Point Drywall Screws, 6" x 1"

These screws are of the lowest quality. 1 in 5 the bit would not fit the screw making it worthless. If that wasn't bad enough the threads were so shallow the srew would spin in the material and not bite like it should. I tossed them in the garbage can.
