Threads
Williams Grade 100 All-Thread Rebar has a cold rolled, continuous, rounded course thread form. Because of the full 360º concentric thread form, Williams All-Thread Rebar should only be bent under special provisions. Williams special thread (deformation) pattern projects ultra high relative rib area at 3 times that of conventional rebar. This provides for superior bond performance in concrete. Threads are available in both right and left hand.
Sizes
Grade 100 All-Thread Rebar is available in 3 diameters from #14 (43 mm) through #20 (64 mm). Other diameters can be provided upon special order. All diameters are available in continuous lengths up to 50’ (15.2 m). Check with your local WFEC Technical Rep for information on availability and lead times.
Welding
Welding of Grade 100 All-Thread Rebar should be approached with caution since no specific provisions have been included to enhance its weldability. Refer to ANSI/AWS D1.4 for proper selections and procedures.
Grade 100 All-Thread Rebar Accessories
All Couplings and Hex Nuts exceed 100% of the bar’s published ultimate strength.
