1 This test was performed on individual specimens of ASTM C62 common brick . Due to the wide variations encountered in the compressive strength of brick , these values should be considered guide values . 2 Allowable loads are based on a factor of safety of 4 . 3 Installation in the mortar joints is outside the scope of the published data . 4 KWIK CON + installed with TKB bits . 5 C _min

, S _min equals 4 inches

Load values are for anchors installed a minimum of sixteen diameters on center and a minimum edge distance of sixteen diameters . Anchor spacing may be reduced to twelve diameters provided loads are reduced by 20 percent . Edge distance may be reduced to six diameters provided loads are reduced by 20 percent in tension and 70 percent in shear .
