in Normal-Weight Concrete
- The allowable loads listed are based on a safety factor of 4.0.
- The minimum concrete thickness is 1 1/2 times the embedment depth.
- Screw is not included.
INSTALLATION
Caution: Oversized holes may make it impossible to set the anchor and will reduce the anchor's load capacity.
- Drill a hole in the base material using the appropriate diameter carbide drill bit as specified in the table. Drill the hole to the specified embedment depth plus 1/8" for flush mounting. Blow the hole clean using compressed air. Overhead installations need not be blown clean.
- Insert anchor into hole. Tap with hammer until flush with surface of base material.
