A captive screw, comprising:
- a screw;
- a press fit nut, to connect to a device at an opening in the device and to accept the screw, including:
- a bottom portion, to be inserted into the opening to engage the device around the opening to connect the press fit nut to the device;
- a top portion;
- and
- a middle portion, wherein the middle portion is smaller in circumference than the top portion;
- and
- a sleeve including a sleeve retainer, wherein the sleeve fits over the screw and the top and middle portions of the press fit nut, and wherein the sleeve is configured to be attached to the press fit nut via the sleeve retainer engaging the middle portion;
- wherein, in an attached state of the sleeve to the press fit nut, the screw is movable relative to the sleeve in an axial direction in response to tightening of the screw.

A captive thumbscrew, comprising:
- a thumbscrew comprising a knurled head and a body;
- a press fit nut, to connect to a device at an opening in the device and to accept the thumbscrew, including:
- a bottom portion, to be inserted into the opening to engage the device around the opening to connect the press fit nut to the device;
- a top portion;
- and
- a middle portion, wherein the middle portion is smaller in circumference than the top portion;
- and
- a sleeve including a protrusion, wherein the sleeve fits over at least a portion of the body of the thumbscrew and the top and middle portions of the press fit nut, and wherein the sleeve is configured to be attached to the press fit nut by the protrusion of the sleeve being received into the middle portion of the press fit nut;
- wherein, in an attached state of the sleeve to the press fit nut, the thumbscrew is movable relative to the sleeve in an axial direction in response to tightening of the thumbscrew.

A captive thumbscrew, comprising:
- a thumbscrew, including a knurled head and a shaft extending from the knurled head, the shaft comprising a protruding section and threads, the protruding section having a larger diameter than the rest of the shaft;
- a press fit nut, to connect to a device at an opening in the device and to accept the thumbscrew, including:
- a bottom portion, to be inserted into the opening to engage the device around the opening to connect the press fit nut to the device;
- a top portion;
- and
- a middle portion, wherein the middle portion is smaller in circumference than the top portion;
- and
- a sleeve including a protrusion, wherein the sleeve fits over the protruding section and threads of the thumbscrew and the top and middle portions of the press fit nut, and wherein the sleeve is configured to be attached to the press fit nut by the protrusion of the sleeve being received into the middle portion of the press fit nut;
- wherein, in an attached state of the sleeve to the press fit nut, the thumbscrew is movable relative to the sleeve in an axial direction in response to tightening of the thumbscrew.
