1. A nut for moving a strip for transporting powder in a selective additive manufacturing apparatus, the nut comprising:
a tapped hole extending along a first axis; and
a slot which passes through a thickness of the nut from an external surface of the nut to an internal surface of the tapped hole and which extends along a plane passing through the first axis over at least one thread pitch of the tapped hole,
wherein the external surface of the nut is a cylinder that comprises two grooves extending along the first axis, each groove being formed by a first rectangular surface parallel to a second axis and by a second rectangular surface parallel to a third axis, the two grooves being positioned in a zone diametrically opposite the slot.
