Anchor Bolt

An anchor bolt is put into concrete to help support a wooden structure. They are very useful in building projects since the concrete provides a very sturdy hold. An anchor bolt can either be installed before or after the concrete is set. When you install before it is set, you will have to have a mechanism for holding it in place.

• Step 1: Before you put the bolt in place you have to mix and pour the concrete.
• Step 2: Drill a hole in a 2x4 that will be long enough to reach across the concrete.
• Step 3: Put the anchor bolt through the 2x4 and prop it up across the concrete. The bolt should partly rest inside of the concrete; you can adjust the depth of the bolt by raising and lowering the board.
• Step 4: After the concrete has dried you can cut off the board.

Installing an Anchor Bolt in Dried Concrete

To install an anchor bolt in dry concrete you must first drill a hole. There are special drills that will cut through concrete without breaking; they can usually be rented at your local hardware store. Make sure you use safety equipment while installing the anchor bolt in dried concrete to protect yourself from flying pieces.
