A sluice-gate wall thimble has a support stem (1, 12) which covers an embedment side of a sluice-gate nut (2) and is fixable to a wall anchor (5, 11). The sluice-gate nut is inside threaded and fixable to an embedment side (16) of a predetermined sluice-gate wall (7) with an axis of the sluice-gate nut being in line concentrically with an axis of a wall-bolt aperture (8) on the predetermined sluice-gate wall. A plurality of the support stems on a plurality of the sluice-gate nuts in line with a plurality of the wall-bolt apertures and fixed to at least one wall anchor are employed first to prevent encroachment of fluid concrete (3) or other foundation material onto inside-diameter threading (4) of the plurality of sluice-gate nuts during construction of a predetermined sluice gate. Then after construction of the predetermined sluice gate, the plurality of support stems are employed to anchor the predetermined sluice-gate wall to the concrete or other foundation material throughout a long and reliable life of sluice-gate-wall attachment to the sluice-gate nuts.
