Twist in the proper direction
Are you turning the right way? Remember, "Righty tighty, Lefty loosy" (which never made sense to me). Most screws are right-handed threads, so you'll turn them anti(counter)-clockwise to remove them. In some situations left-hand thread screws are used (usually to prevent screws from loosening due to rotational forces), so you'...
drilled a 6 mm hole in the masonry, then used brown wall plugs and #8 screws
Your hole was too small and the screw was the wrong size or type. A #8 screw has a 4mm diameter.
Brown wall plugs fit into a hole made by a 7mm drill bit and are for screw sizes 10 - 14

If you are concerned about the presence of wiring near where you are installing this, grab yourself a stud finder with "live wire" detection from your local hardware store. Entry level models are inexpensive. This way, you can find the studs and the wires. More expensive models may also detect other services (e.g. metal plumbing or gas pipes).

If you can use a drill with a screwdriver bit to drive a screw, then most of the time, use it.
Here's when you might be smarter to use a screwdriver:
The screw is going into a pre-tapped (threaded) hole in metal, or plastic, or any soft material.
Always at least start such screws by hand -- so that you can avoid cross-threading them.
Putting screws into ...
It is possible that there are several reasons for the screw head destruction.
You may be using an electrical tool that is not at all suitable for driving screws. Some tools designed for drilling holes are not going to offer enough torque at a low enough speed to properly drive screws. If your tool starts out with a huge burst of speed it can almost ...
It is called a "hex key", "Allen key", or "Allen wrench".
You can also find socket wrench tools with this hexagonal drive shape. Hex key socket wrenches are almost always stronger than Allen keys, and less likely to round out the screw head.
Both the fasteners and the tools shipped with Ikea furniture kits are necessarily the cheapest that can still do ...
This is a tamper proof torx screw. There are torx bits with a hole in the center that will remove them, if you are bold you can try smacking the center pin with a punch at an angle (small ones usually snap off) and then a standard torx bit can be used to remove it. Check online and I bet you can find a tamper proof bit kit for under 15$.
You may have some luck with a screw extractor. They come in various styles - here are two of them:
The extractors are designed to screw themselves down into the head of the screw while at the same time applying torque on the screw in the direction that would loosen the screw. Your described screw had a hex socket type hole so the extractor may be ready to ...
It looks like a spanner tamper-proof security bolt. Either buy a set of tamper-proof security bits, or modify a cheap standard slotted screwdriver with a dremel tool. Here is a cheap set: https://www.amazon.com/Performance-Tool-W8659-Security-32-Piece/dp/B002KS19PK/ A good chance that something in this set will work, but no guarantee.
The bit that you are asking about is what is called a "concave Phillips" or "inverted Phillips" bit. They are used for removing screws that look like this:

The cross pattern on the screw head is actually raised.
I wouldn't worry too much. Modern electrical standards have wire stapled an inch and a bit back from the interior of the drywall. If your screws are less than 1.5" long, you shouldn't hit anything. If you are pre-drilling for drywall plugs, only go 5/8" in.
It's ideal (and still safe) if you get one screw into a stud. There should be one either on the left ...
It is a simple security slot headed screw.
A flat headed screw has part of the slot filled in to make it difficult for the average joe to undo.
Either purchase a set of security bits or take an old screwdriver and grind out the matching part on the screwdriver blade so it fits neatly.
Abrasive paste as sold in car repair shops to use when grinding in valves in cylinder heads is great for screw heads that are 'worn'. Place a small dab on the screwdriver head before trying to unscrew the item. The friction from the abrasive in the paste will help the screwdriver 'grab' the worn screw slot..
Is this an impact driver?
Lower the torque setting on the drill.
Use the correct sized bit for the screw. For Phillips head screws there are several sizes. If you are using a Pozidriv screw, use a Pozidriv bit. Sometimes you can use a square drive bit with Pozidriv, but using a Phillips bit will generally cause the bits to cam out.
Try using ...
If its metal on metal you can try heating the area or cooling it with ice. Metal expands and contracts with temperature change (works great on spark plugs too!).
For screw heads starting to strip, a piece of bicycle inner tube or rubberband between the head and driver bit helps it from stripping further.
You realize that they make screwdriver bits to go into drills that will also go into the chuck of your hand drill. You can get longer bits that will fit easily into the chuck, for example:
You can also get magnetic extenders that will fit into the chuck and then hold a standard bit:

"M" screws are all metric, by standard. The number following the M is the outer diameter of the screw threads, in millimeters, so an M4 screw's threads have an outer diameter of 4mm.
See Wikipedia for more information.
The Phillips screwdriver size is based on the size at the very tip. Based on diagrams of the tip from the original Phillips patent (shown in one of the links to sizes.com), I'm guessing that the relevant physical size is the cross you see when you point the screwdriver at your nose (as though it were a screw) and look at it end-on, or something directly ...
You can but it would be easier and more efficient to bring a manual wrench. A wrench or ratchet will let you apply your torque closer to the same plane as the head of the bolt. Turning the drill will be like a ratchet with an extension on it. Use the right tool for the job, your tools, your watch, and your wallet will thank you for it!
Stripping a screw is indeed a terrible thing to do. It is best to avoid the problem of stripped screws by not stripping them in the first place, but you should also be prepared to deal with a stripped or rusted screw in the event that you have to deal with one.
Your first step should be to look at the screw's head and find several screws that you might ...
For screws that held the original hinge in an old wood door, and would not budge, even with the advice above, I aimed a hair dryer at the screw for a few minutes (thinking that perhaps the wood was damp and that was holding the screw in; could also have been something about heat since I often run hot water over stuck screw tops). Anyway, it worked, with only ...
00 refers to the size and angle of the tip. It doesn't say how thick the tip becomes before merging into the shaft. So, yes, these could both be 00 sized, if they fit the same screws; the thicker one just (a) will fit larger 00 screws better than the small one would and (b) won't fit into as small an opening.
Screwdriver bits are generally considered consumable. Regardless of the brand, they eventually break/wear out. Hardware stores sell them in packs of 5-10 for exactly that reason. I wouldn't put too much stock in what kind of tool the bit originally came with.
The only exception is if you're using an impact driver you might want to be a little more picky. ...
Congratulations on becoming a home owner. You will soon learn to use lots of tools if you plan to do any DIY projects around the house.
Most locksets only require a #2 Phillips screwdriver. You should not need any special or expensive tools. Just read the directions and follow them. Changing locks is very simple, usually just two screws that hold the inner ...
First of all, make sure you are using the correct bit on your electric screwdriver. If the screws have a cross-shaped head, check whether you need a Philips or a Pozidriv bit for it. Pozidriv has an additional "X" shape on the screw, and using the wrong kind of bit will cause slippage. There are many online guides how to identify the proper bit, such as this ...
