RUKAVAC S NAVOJEM ZA NAGLAVAK

摘要

A rod of circular cross-section is provided on opposite sides with two sets of equispaced ribs, each extending over substantially 180 DEG , which are tangentially faired at their ends into the rod surface at a median plane separating the two sets. The ribs of these sets are relatively offset by half their spacing whereby they can mate with a female helical thread of corresponding pitch in a coupling nut or anchor sleeve.
