Identify the spot on the brick where you would like to hang your item and install your bolt. Choose a spot in the middle of the brick rather than the mortar. The brick will be a sturdier choice. Mark the spot with a pencil.
Choose a molly and bolt. A molly is a bracket that expands when you screw the bolt into place, creating a stronger grip on the brick. Mollies and bolts are rated by the weight of the object they can support. Choose a molly and bolt that can support the weight of your object.
Drill a pilot hole at the pencil mark. Use a masonry bit to drill a hole in the wall. Make sure you use a masonry bit rather than a regular drill bit. Regular drill bits will be ruined when used on brick. Choose a masonry bit that is the appropriate size for your project. The packaging on the bolt should indicate what size drill bit to use with your bolt.
Insert a molly into the hole. Use a rubber mallet to gently tap the molly into the hole until it is flush with the brick.
Attach the bolt to the molly. Use a screwdriver to attach the bolt into the molly. If you are hanging an item with a bracket, hold the bracket over the molly and attach the bracket to the wall with the screws.
