Asked by Gary May 1, 2020It is up to the Designer to specify the anchor bolt type, length and embedment based on concrete strength, bolt location/spacing, local building codes, etc. I will point out that wedge anchors are installed in existing concrete. Please feel free to contact our Engineering Support Department at 800-999-5099 to discuss further (with more information, they can share possible anchor options). Thank you!
DOES THIS ANCHOR USE A 1/2" CONCRETE DRILL BIT? OR SHOULD I GOT 1 SIZE LARGER?
