Tension and Shear Loads for Threaded Rod Anchors in Lightweight, Medium-Weight and Normal-Weight Hollow CMU
  1. Threaded rods must comply with ASTM F1554 Grade 36 minimum.
  2. Values for 8-inch wide concrete masonry units (CMU) with a minimum specified compressive strength of masonry, f'm, at 28 days is 1500 psi.
  3. Embedment depth is measured from the outside face of the concrete masonry unit for installations through a face shell.
  4. Allowable loads may not be increased for short-term loading due to wind forces or seismic forces.
  5. Refer to in-service temperature sensitivity chart for allowable load adjustment for temperature.
  6. The tabulated allowable loads are based on a safety factor of 5.0 for installations under the IBC and IRC. For installations under the UBC use a safety factor of 4.0 (multiply the tabulated allowable loads by 1.25).
  7. Anchors must be spaced a minimum distance of four times the anchor embedment.
  8. Screen tubes not for use with SET1.7KT or SET1.7KTA.
  9. Set drill to rotation-only mode when drilling into hollow CMU.

  1. Threaded rods must comply with ASTM F1554 Grade 36 minimum.
  2. The tabulated allowable loads are based on a safety factor of 5.0 for installations under the IBC and IRC.
  3. Edge distances may be reduced to 4" with a corresponding 32% reduction in tension capacity. Shear capacity is unaffected.
  4. Values for 8-inch wide, lightweight, medium-weight and normal-weight concrete masonry units with min. compressive strength of 1,900 psi and 1 1/4" thick face shell.
  5. Embedment depth is measured from the outside face of the concrete masonry unit.
  6. Refer to in-service temperature sensitivity chart for allowable load adjustment for temperature.
  7. Allowable loads may not be increased for short-term loading due to wind or seismic forces. Wall design must satisfy applicable design standards and be capable of withstanding applied loads.
  8. Screen tubes not for use with SET1.7KTA.
  9. Set drill to rotation-only mode when drilling into hollow CMU.
