Advantages
  • Lighter weights with higher strengths and lower costs
  • Continuously threaded for maximum versatility or threaded on ends only
  • Durable threads and components capable of developing the full capacity of the bar
  • Right and left hand capability for use with sleeve nuts and turnbuckles
  • Up to 50 foot stock lengths
  • Several options of corrosion protection from simple to multiple protection for aggressive environments

Williams Grade 150 KSI All-Thread-Bar
Williams 150 KSI All-Thread Bar consist of high tensile steel available in seven diameters from 1” (26 mm) to 3” (75 mm) with guaranteed tensile strengths up to 969 kips (4311 kN). Lengths of up to 50 feet are available on most diameters. Bars are provided with cold rolled threads over all or a portion of the bar’s length. All tension components for the systems are designed to develop 100% of the bars published ultimate strength. Bars are produced to ASTM A-722-07 physical standards. Williams All-Thread 150 KSI Bar must never be welded, subjected to the high heat of a torch, or used as a ground. Field cutting should be done with an abrasive wheel or band saw. All components of the systems are designed and manufactured in the United States and have been field proven around the world.
Williams Grade 75 All-Thread Rebar
Williams 75 All-Thread Rebar is a continuously threaded bar specially designed to be used with fasteners. Common applications for the Grade 75 All-Thread Rebar are marie tie rods and ground anchors. All-Thread Rebar is available in 11 diameters from #6 (20 mm) through #28 (89 mm) with ultimate tensile strengths up to 961 kips (4274 kN) and lengths up to 50 feet. The bars are provided with a special thread designed to meet the requirements of ASTM A615 and Canadian Rebar Specifications CSA-G30.18-M92.
Threads are cold rolled on the bar over all or a portion of the length as desired. Because of the full 360 degrees concentric thread, Williams All-Thread Rebar should only be bent under special provisions. All tension components are designed to develop 100% of the bars published ultimate strength. All components for the system are manufactured in North America.

Conversion Chart - Compare for Yourself!
Williams All-Thread-Bars are more economical than heavier ASTM A36 or upset threaded rods. All-Thread Bars are usually on the the order of 10-30% less expensive than A36 tie rods when bar comparisons are based on equivalent ultimate strengths. Not only are the bars less expensive but since the bars are smaller, additional savings may result with the connectors and material freight. In addition, since smaller diameter bars have smaller surface areas than larger bars, corrosion protection may be more economical. It is not uncommon to see cost savings up to 30% when comparing the Williams All-Thread tie rod systems to upset threaded or A36 rod systems. Bars shown actual size.
