Threaded rods, also known as threaded bars or ATR (All Thread Rods), are cylindrical straight rods with continuous external threads along their entire length. Threaded rods in bar form are also referred to by other names, including fully threaded studding, screw rod, redi-rod, TFL, and continuous threaded rod.
Threaded rods can be cut to length, chamfered at both ends, and shortened threaded rods are also referred to as studs. Common sizes for full-threaded rods include 3 feet, 6 feet, 10 feet, and 12 feet.
Threaded rods are easy and efficient to install, typically used in conjunction with nuts and washers, and are suitable for connecting, reinforcing, and supporting industrial structures in space-constrained environments.
