Patent ID: 8220176

Claim:
A gauge for mounting a screw in a cage nut with an aim of assembling at least two parts, the screw including a head and a shank with a smooth intermediate section and a threaded end, and the cage nut including a threaded bore and an unthreaded bore delimited by a nut shoulder disposed at an interior of the cage nut, the gauge comprising a shank with a smooth section having graduations and with a threaded end including threading and a gauge abutment shoulder, the threading being similar to threading of the screw, and a sleeve slidably mounted on said smooth section, an axial length of said sleeve and a distribution of said graduations being configured and positioned so that when the shank of said gauge is screwed into the cage nut such that said gauge abutment shoulder abuts the nut shoulder and said sleeve is pressed against one of said two parts, the graduation indicated by said sleeve on said smooth portion is representative of a distance separating the threaded bore of the cage nut from an outer surface of the part situated facing away from the cage nut.
