A fastener assembly for installing valve devices and the like on one side of a mounting plate by bolts were the bolt holes are without threads and the opposite side of the mounting face is inaccessible for holding a bolt head or nut from turning. The fastener assembly includes at least one fastener plate and a minimum of two threaded bolts affixed thereto, so that the threaded portion of the bolts affixed thereto, so that the threaded portion of the bolts projects through bolt holes in the mounting plate. The at least one fastener plate may be a split ring. A retaining washer is threaded onto the projecting bolt threads to retain the fastener plate in place while the valve device is being installed onto the projecting bolt threads on which lock nuts are subsequently screwed to secure the installation. Tightening of the lock nuts without consequent rotation of the fastener plate bolts is achieved by reason of the torque imparted to one bolt being transferred via the fastener plate to the other bolt thereof, which is constrained from moving in an arcuate path by the hole in which it is disposed to thereby prevent rotation of the one bolt as the nut is screwed down.
Dispositif de montage servant à boulonner des appareils de robinetterie et autres appareils du même genre sur une plaque de montage dont la face opposée à la face de montage est inaccessible. Le dispositif de montage comporte au moins une plaque de fixation à laquelle sont fixés au moins deux boulons dont les tiges filetées émergent du côté de la face de montage de la plaque. Cette plaque de montage peut être sous forme de segment fendu. Une rondelle de retenue est enfilée chacune des tiges filetées émergeant de la plaque pour maintenir celle-ci en place durant le montage de l'appareil de robinetterie; des écrous de blocage sont ensuite vissés sur les tiges filetées pour compléter l'assemblage. Le serrage des écrous de blocage sans mouvement de rotation de la plaque de montage est possible du fait que le couple exercé sur chaque boulon est transmis à l'autre boulon par l'intermédiaire de la plaque de montage.
