1. How to renew and reuse a screw

The result of taking out and reseating a screw is usually a damaged slot. This is especially true if your screwdriver blade did not fit the screw. You can try to restore the old screw if you do not have a new screw to replace it. Start this by making the slots of the screw deeper. This can be done by using a hacksaw to cut into the slots. If the screw is not in the hole when you go to repair it, you will need to use a vise to hold the screw. Do not use your fingers to hold the screw. This protects you from injury as well as the threads.

Imagine you need to remove a Phillips-head screw, but slots only have a screwdriver that will remove slots. You can extend one of the slots all the way across the head with a hacksaw. This will allow you to remove the screw with your screwdriver.

2. Remove clogged screw
If a screw has been clogged over with paint, dig out the paint with a scratch awl.

3. Trick to keeping track of where screws go
When working on a large project, it can become easy to lose track of where your screws go when putting the project back together. This trick can help you keep track of your screws. Grab a piece of corrugated cardboard that has slots in the side. Use these slots to keep your screws in order of when you took the screws off your item. Sometimes writing notes on the side of the cardboard can help you when reassembling.

4. Restore a stripped screw hole
Plug a hole with a wooden golf tee. Fill in the hole with glue and put the plug into hole. Once the glue has dried, you will be able to drill out the hole and drive the new screw in.
