All-Thread Bar Data
Williams All-Thread-Bars are used with the Ultrabond adhesive for unmatched anchoring versatility and capacities. The Ultrabond adhesive provides a molecular bond to the substrate while coating and protecting the embedded dowel. Epoxy Adhesive concrete anchors should be designed utilizing methods in Chapter 17 of the latest edition of ACI 318. Bars can be ordered cut to length or in stock lengths up to 50 feet for job-site cutting. Williams offers hex nuts, plates and washers with each anchor bar. Williams recommends epoxy anchors to only be specified as passive (non-prestressed) anchors.
Williams bars should never be torch cut.

(1) Recommend embedment depths are based on ACI 318-14, Section 17.3.2.3 with Maximum embedment depth not to exceed 20 bar diameters. Greater embedments depths may be considered provided each anchor is tested to verify adequate bond strength.
(2) Volumes are based on the Maximum Recommended Embedment Depth and the recommended drill hole diameter.
For different embedment depths, the volume can be estimated by linear interpolation
* Bars larger than 1-1/4” are not included within ESR-4094 for Ultrabond HS-1CC or ESR-4535 for Ultrabond HYB-2CC.
