Molly bolts are wall anchors that can be used to hang moderate weights on walls. They are sturdier than other anchors since the anchor expands at the back once lodged in the wall. This allows for a firmer hold in the wall and the bolt can then take a heavier weight without dislodging. Molly bolts can be made of plastic or metal depending on your preference. Plastic molly bolts are more difficult to use and are preferred by professionals. They are also fairly easy to install though they do need to be installed in hollow walls since the anchor needs a place to expand at the back.

Step 1 - Get Organized

Choose an appropriate Molly bolt and a screw. You can find them at any hardware store. Keep the object you need hanging ready. Get a clearly visible marker or chalk along with a drill and a screwdriver. Make sure the area that you will be working in is clear and has room enough for you to move around. Ensure that no pets or children can disturb you while you work as dropping a running drill machine can be unpleasant.

Step 2 - Prepare the Area

Find an appropriate spot in the hollow wall to hang your item. Have someone help you hold it up to make sure that you have the right spot. This is important since you don’t want to damage the wall by drilling too many holes. Use a measuring tape if necessary to find the center to hang your object so that it sits just right. The spot should not be too low or high and even a minor misjudgment in the placement can spoil the final effect.

Step 3 - Drill the Spot

Mark the spot you have chosen with a marker. Using the drill create a hole ensuring that it is big enough to drive the Molly bolt through. The hole should be slightly larger than the anchor. If the hole is too small then the bolt may get stuck and it will be difficult to pull it back out without damaging the wall. If this happens then use pliers to dislodge the anchor.

Step 4 - Install the Bolt

Take the screw and insert it into the Molly bolt. Push it into the space you created. Screw the bolt in place using a screwdriver. You can even use a manual screwdriver to do this. Don’t tighten it too much. The Molly bolt will flare into place at the back of the wall creating an anchor.

Step 5 - Hang the Object

The Molly bolt is now ready for use. You can hang your desired object but make sure it’s not too heavy for the bolt or it may rip the plaster and the whole thing will come crashing down. You can now clear the space of clutter and enjoy your handy work.
