A:Answer The only needed screw would be the one that should already be on your motherboard across from the M2 slot. Some motherboards have a screw and some have a little rubber insert, which has a cone shape with a flat ring base on top that will secure the end of the SSD, so it doesnt swing out and dismount from the M2 slot. Ive added a picture to show you the screw that should have come installed with your motherboard
