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. Starlocks are generally available in spring steel and many are also supplied in stainless steel. These fasteners can be supplied in blue and varnish BV or in mechanical zinc plated D finishes.
