2x M5x30 Hex Socketed Machine Screw/Bolt

2x M5 Hex Nut (Be sure both bolt & nut are the same thread pitch.)

Notes: 

1) The height of the Standard mount is (from the top of the picatinny rail to the bottom of the red dot's mounting surface) is5.53mm. That means if you attach the +20mm riser, it's actual height is 25.53mm. The millimeter designations for the risers are based on the addition to the Standard mount's height, not the riser's height itself.
