Abstract

A fluid-tight, adjustable and self-locking threaded connection assembly comprising a nut and a bolt. The nut which is adapted to be fixed to a first structural member has a bore comprising a threaded portion and a smooth cylindrical portion. The bolt which is adapted to be removably connected to a second structural member has an intermediate portion provided with a plurality of circumferential sealing lips. The sealing lips are dimensioned with respect to said smooth cylindrical portion of the nut bore such that it is slidingly urged against said smooth portion of the nut bore when the bolt is adjusted relative to the nut. As a result thereof the threaded connection assembly is fluid-tight and self-locking while being adjustable.
