The Earthbound System is proud to feature domestic and traceable threaded rod.
|
| Earthbound Threaded Rod Features and Benefits: |
| ● |
Made in the USA with 100% traceability of the materials and manufacturing processes. |
| ● |
Zinc plated rod is available for low carbon A36/A307 (60 ksi) applications. Plain or black rod is also available. |
| ● |
High Strength (HS) rod A193B7 (125 ksi) is always black to avoid confusion with zinc plated low carbon A36/A307 on a job site. |
| ● |
All threaded rod is UNC (Unified National Coarse) threaded. |
| ● |
Hot Dip Galvanized A449 and Stainless Steel threaded rod is available for pressure or fire treated
lumber. |
| ● |
Other threaded rod specifications available upon request. |

| NOTES: |
| 1. |
STANDARD STRENGTH ROD / ASTM A36/A307: Fu = 60,000 PSI. Fy = 43,000 PSI. "UNC" THREAD PITCH. |
| 2. |
HIGH STRENGTH ROD / ASTM A193B7: Fu = 125,000 PSI. Fy = 105,000 PSI. "UNC" THREAD PITCH. |
| 3. |
TENSION LOADS ARE CALCULATED FROM THE FOLLOWING EQUATIONS:
| A. |
(100) THREADED ROD CAPACITY = [(0.33 Fu * Nominal Rod Area)] PER AISC 9th EDITION (UBC97 thru IBC2003) |
| B. |
(133) COLUMN CONTAINS 1/3 SEISMIC DURATION INCREASE OF (100) LOADS ALLOWED UNDER UBC 97. |
| C. |
(IBC 2006) IBC 2006 THREADED ROD CAPACITY = [(0.375 Fu * Nominal Rod Area)] PER AISC 2005/13th EDITION (IBC2006) |
| D. |
(0.125 MAX) THREADED ROD CAPACITY BASED ON 0.125 INCHES MAX ELONGATION OVER 10 FEET. MoE = 29E6 PSI. |
| E. |
CANADA USE ONLY: FACTORED RESISTANCES SHOWN ARE THE LOWER OF 13.2.(a)(i), 13.2.(a)(ii) and 13.12.1.2 of CSA S16-01. |
|
| 4. |
"UNC" = UNIFIED NATIONAL COARSE THREADED ROD PITCH. |
