Abstract
A nut and washer unit for attachment of a plumbing faucet or fixture permits rapid and easy mounting at a supporting structure. The nut is placed on the shank before the faucet or fixture is dropped through the mounting hole. A C-shaped washer is positioned from below, between the nut and the mounting structure. An axially separable coupling between the nut and washer achieves initial placement of both parts at the mounting structure by simple hand rotation of the nut. Final clamping is achieved by engagement of wings formed on the washer, rotation of the washer causing corresponding rotation of the nut and, hence, advancement of both parts into clamping position.
