| "p" is the minimum threadbar protrusion to accommodate prestressing, proof loading or coupling, "p"=½c+½ (12.7 mm). * Couplers and nuts develop 100 % of guaranteed ultimate strength. Resin anchors using DYWIDAG Prestressing Steel may be proof stressed to 80 % of the guaranteed ultimate strength of the prestressing steel. Lock off force should not exceed 70 % of the guaranteed ultimate strength of the prestressing steel. | ||||||||||||||||||||

All couplers and hex nuts develop 100 % of the normal ultimate strength of the bar. 63 mm bars and hardware available in Grade 80 material only. "d" is measured across nut flats Resin anchors using DYWIDAG Reinforcing Steel may be proof stressed to 90 % of the guaranteed yield strength of the reinforcing steel. The final working force varies with the application and function of the anchors. | ||||||||||||||||||||

| *Ratio of resin column length after insertion of DYWIDAG THREADBAR® to resin column length before inserting DYWIDAG THREADBAR®. Resin yield chart information provided by Celtite, Inc. Yields are calculated; no waste or allowance for over-drilling is included. Site trials should be conducted to determine actual resin requirements. Example: When using 1" (26 mm) DYWIDAG THREADBAR® in 1½" (38 mm) diameter hole with 1¼" (32 mm) diameter resin cartridge, resin yield multiplier is 1.27. A 12" (305 mm) resin column yields 15" (381 mm) of resin after the insertion of the DYWIDAG THREADBAR®. | ||||||||||||||||
