Things You'll Need. Related Articles. Article Summary. Part 1. Put on safety gear. Using a screw extractor involves drilling into metal. The last thing you want is a flying shard of metal in your eye. Wear safety goggles made with polycarbonate lenses. Align a center punch over the screw. A center punch is a metal cylinder that looks like a pen. You can find them at any hardware store.
With one hand, hold the metal tip against the center of the screw head. Indent the screw by hammering in the punch. Pick up a hammer in your free hand and use it to tap the top of the punch. Strike it very lightly. This guides your drill bit into the center of the screw. If the screw is in a tight space, use a small metal drill bit and a right angle drill.
Apply a drop of thread cutting oil to the screw. Thread cutting oil is sold in big jugs at hardware stores, but you only need a drop. Tip the bottle over to splash a little bit onto the screw head. Cutting oil lubricates the metal, which means less time spent drilling and less wear and tear for your drill bit. Household oils will help but offer less protection to the drill bit. Add a drop of penetrating oil to rusty screws. Penetrating oil is needed for rusted screws or ones attached to metal surfaces.
It loosens the screw, making it easier to remove. Add a drop of it onto the screw head on top of the thread cutting oil. Part 2. Select a drill bit slightly smaller than the screw. Hold the drill bits up to the screw or fastener you need to remove. The right one will be slightly less wide than the screw head.
When you find the right one, attach it to your drill. Line the drill bit up with the center of the screw. Place the drill bit in the divot you created earlier. Move slowly as you begin to drill. Too much force will damage the screw. Focus on holding the drill bit steady so it drills straight down into the screw head.
Drill a hole for the extractor. The depth depends on the screw extractor you have. Hold up the extractor to compare it to the hole you drilled. Part 3. Insert the extractor into the drilled hole. The spiral end of the extractor goes into the hole. No one screw or fastening could possibly serve as a one-size-fits-all solution, because there are simply too many different needs and applications for screws and fasteners.
These are just a few of the different types of screws. In some cases, you may find a screw is classified by a combination of terms. For example, you might find that you need a slotted flathead metal screw. The screw creates its own threads as it is installed and remains tightly in place despite any activity or vibrations. This is incredibly important in large construction projects where getting the project done on time is of the utmost importance. These screws are also reliable, as they hold materials together firmly and have a long service life.
Installing self-tapping screws with a coating can also prevent discoloration of the material due to rust or corrosion, making these fasteners ideal for harsh environments. At All Points Fasteners , we work each day with service contractors to ensure they have the screws they need to deliver outstanding results. We specialize in tracking down even the most difficult-to-find fastening solutions — so our clients always have access to exactly what they need.

OK, what's this "Screw Finder" thing? Post by Zimzim » Mon Aug 15, am I've had a set of drill and screw driver bits for about 5 years now, and it contains a mystery item call "Screw Finder".
Can someone put me out my misery and finally tell me what it's supposed to do AND how it works.
