For temporarily supporting an end of one sheet and/or of adjacent ends of two separate sheets of plasterboard (drywall), plywood or the like, in a raised overhead state and position while raising and securing opposite end(s) thereof to overhead rafters, beams or the like, there is provided an overhead sheet-installation support tool inclusive of a forwardly-directed tapered threaded screw having a longitudinal axis along its length-dimension with a tapered forward distal end, having at its forward distal end screw threads; there is a handle structure extending rearwardly a suitable height-distance for grasping and handling, the handle having opposite flattened sides spaced-apart by a minor handle-thickness, and with forward shoulders of handle structure having laterally-extending shoulders angled rearwardly at laterally outwardly distal ends thereof and the shoulders having a flange along at-least a forward edge of the shoulders with the flange extending at an angle of about 90 degrees relative to the flattened spaced-apart sides, and an arcuate flat-faced support member being mounted adjustably on one of the flattened sides positioned and adapted to be intermittently adjusted such that an end thereof is moveable to and from a lower face of a support beam and/or ceiling located in juxtaposition to an outer end portion of one of the laterally-extending shoulders, and a linear flat-faced support element adjustably mounted on one of the flattened sides positioned to length-wise extend and be adjusted in along a direction extending substantially parallel to the a longitudinal axis of a shaft or shank portion of the threaded screw such that an upper flattened end of the linear flat-faced support element is movable to and from position(s) of support of a sheet-support level at which desirably a sheet would be thereby be locked-against a beam while being nailed or otherwise secured to the beam.
