For SI: 1 inch = 25.4 mm, 1 lbf = 4.45 N, 1 psi = 6.89 kPa.
1
All values are for anchors installed in fully grouted concrete masonry walls with minimum masonry strength of 1500 psi. Concrete masonry units must be light-,
medium-, or normal-weight conforming to ASTM C90. Allowable loads have been calculated using a safety factor of 5.
2
Anchors may be installed in any location in the face of the masonry wall (cell, web, joints). Anchors are limited to one per masonry cell.
3
Embedment depth is measured from the outside face of the concrete masonry unit.
4
The critical spacing, s
cr
, is the anchor spacing where full load values in the table may be used. The minimum spacing, s
min
, is the minimum anchor spacing for
which values are available and installation is recommended. Spacing is measured from the center of one anchor to the center of an adjacent anchor.
5
The critical edge distance, c
cr
, is the edge distance where full load values in the table may be used. The minimum edge distance, c
min
, is the minimum edge
distance for which values are available and installation is permitted. Edge distance is measured from the center of the anchor to the closest edge (See Figure
2).
6
Load reduction factors are multiplicative; both spacing and edge distance load reduction factors must be considered.
7
Load values for anchors installed at less than s
cr
and c
cr
must be multiplied by the appropriate load reduction factor based on actual edge distance (c) or
spacing (s).
8
Linear interpolation of load values between minimum spacing (s
min
) and critical spacing (s
cr
) and between minimum edge distance (c
min
) and critical edge
distance (c
cr
) is permitted.
9
Concrete masonry thickness must be equal to or greater than 1.5 times the anchor embedment depth.
10
Anchors are not recognized for resisting earthquake forces. When using the basic load combinations in accordance with IBC Section 1605.3.1, or the
alternative basic load combinations in IBC Section 1605.3.2, tabulated allowable loads must not be increased for wind loading.
11
Allowable loads must be the lesser of the adjusted masonry or bond values tabulated above and the steel values given in Table 4.
12
Tabulated allowable bond loads must be adjusted for increased base material temperatures in accordance with Figure 1, as applicable.
13
For combined loading, see Section 4.1.2.

All values are for anchors installed in fully grouted concrete masonry with minimum masonry strength of 1500 psi. Concrete masonry units must be light-,

2
When using the basic load combinations in accordance with IBC Section 1605.3.1, tabulated allowable loads must not be increased for seismic or wind
loading. For the 2021, 2018, 2015 and 2012 IBC, the allowable loads or load combinations must not be adjusted.
3
One anchor must be permitted to be installed in each CMU block. Refer to Figure 3 for an illustration of the anchor location for which the tabulated values are
applicable.
4
The tabulated edge distance is measured from the anchor centerline to the edge of the CMU block as depicted in Figure 3.
5
Anchors must be installed into the grouted cell. Anchors are not permitted to be installed in a head joint, flange or web of the concrete masonry unit.
6
Linear interpolation of load values between the two tabulated edge distances is permitted, as applicable
7
Allowable loads must be the lesser of the adjusted masonry or bond values tabulated above and the steel values given in Tables 4 and 5.
8
Tabulated allowable bond loads must be adjusted for increased base material temperatures in accordance with Figure 1, as applicable.
