The Inlock® Fastener is an effective means of anchoring a thread stud into a tube.

Diagram of an inlock washer

The method employed for assembly is to screw two or more inlocks on to a stud and then to press this assembly into the tube leaving a threaded portion protruding. The number of inlocks used is dependent upon the load requirements, but a minimum of two, suitably spaced, must be used to align the stud with the bore of the tube.
