Coupling to Stud
 ä Testing Accessories:Threaded Coupling (Male - Female)
Each coupling is made from high strength steel. The threaded stud section of the coupling is made from rolled threads, if possible. The rolled thread increases the strength while reducing micro-cracks. The ends have been machine chamfered. Each coupling has a spanner wrench hole for assembly and removal.
