Threaded rod, also called all-thread, is threaded end to end and cut to length on the job. Electricians, plumbers and HVAC crews use it to hang strut, pipe, duct and cable tray from drop-in anchors and beam clamps. Machine shops and mechanics use studs and stud bolts for flanges, manifolds and fixtures. This section covers low-carbon steel rod in zinc and galvanized finishes, 18-8 and 316 stainless rod, ASTM A193 B7 alloy rod for high-strength flange work, double end studs and full-thread stud bolts.
