How it works

Nuts and couplers engage the threads

Thread matching nuts or couplers onto the rod. Plates and other connected parts seat at the assembly ends, with nuts tightened to create the working connection.

Threaded Rods This page
Choose it for rod-and-plate foundation assemblies, suspensions and adjustable supports, where thread along the full length is useful.
Tie Rods (Double Ended)
Choose it when opposing form faces need to be drawn together and held by one rod through the wall.

Common applications

Where it is used.

Application

Rod-and-plate temporary restraint

Connects threaded plates and mating nuts in rod-and-plate assemblies for form restraint.

Application

Adjustable suspension and support

Threads through couplers and support brackets for adjustable positioning in concrete work.

Application

Temporary bracing and tie assemblies

Provides a threaded rod element for site-assembled bracing and temporary ties.

What are threaded rods called in other regions?

Threaded Rods are called all-thread rods in the US, studding in the UK, tige filetée in France, Gewindestange in German, and barra roscada in Spanish. They are manufactured in multiple thread standards for different applications.

What thread types and specifications do threaded rods have?

Threaded Rods come in diameters from 1/4 to 2-1/2 inches (M6–M60 metric) with UNC, BSW, or DIN threads in V, coil, or square acme profiles. They are available per ASTM A307 or DIN 975 with stainless or zinc plated finishes.

Concrete systems

Continuous-thread rod for assemblies

Threaded Rods connect matching nuts, couplers and Plate Washers in temporary restraint and rod-and-plate assemblies. Tie Rods provide double-ended versions for form-tie work.
