How to Use Anchor Bolts in Concrete
- 1). Read the installation instructions packaged with your anchor bolts to determine the correct-size masonry drill bit needed to drill the hole and the depth you need to drill the hole.
- 2). Insert the masonry drill bit into the hammer drill, set the depth gauge to the dimension specified in the anchor bolt installation instructions, and put on your safety glasses.
- 3). Drill the hole into the concrete. Stop drilling when the depth gauge contacts the concrete's surface.
- 4). Remove debris from the hole by inserting the round wire brush into the hole, rotating the brush handle and pulling the wire brush out of the concrete.
- 5). Insert the nozzle of the air bulb into the hole in the concrete and push the nozzle to the bottom of the hole.
- 6). Squeeze the air bulb to clear the hole of concrete dust. Stop forcing air into the hole when there is no more dust emitting from the hole.
- 7). Place a flat washer over the threaded end of the anchor bolt and then thread a hex nut onto the anchor bolt threads until the top of the hex nut rests flush with the top of the anchor bolt.
- 8). Slide the anchor bolt into the hole you drilled in the concrete, with the threaded end of the anchor bolt facing toward you.
- 9). Hit the nut with a hammer to force the anchor bolt to the bottom of the hole.

Place the appropriate socket onto the click-style torque wrench and set the torque on the wrench as specified in the anchor bolt installation instructions. - 11
Tighten the nut on the anchor bolt with the torque wrench until you hear a click from the wrench. Do not over-torque the nut, as this will compromise the holding strength of the anchor bolt. - 12
Remove the nut and washer from the anchor bolt and the anchor bolt is ready to use.
