Hand Tools

So that bolts are tight enough .but not overtight, and so many close bolts can all be the same pressure.

No, it remains the same.

Most electric power tools as we know them were developed in WW2. They started becoming available for home use in the late 1940's.

You cannot chisel, saw or hammer with it.

That's a pretty big drill bit, -it drills a hole just a tad larger than 3 3/8 inch wide.

It's what north Americans call a bench vice. A fixed tool with one fixed face and another movable face that can grip and hold objects to be worked on.

For various reasons. Not adjust the milling machine. Sudden collision with the workpiece. Hard sex of the workpiece. High heat during cutting.

You use a torque wrench for tightening bolts to an exact pressure. This is particularly important in things where many bolts must all be the same tightness, such as cylinder heads in engines, and parts of transmissions.

Most 'plug in ' power tools are rated at 6-13 amps.

Most likely something around 12 mm or !/2 inch. Try slipping various wrenches on till you find the correct securely fitting one. This will broaden your knowledge of how to fix autos. - Oh, one other hint on removing hood hinges or latches. -They must go back in exactly the same position, so I always run a 'Sharpie' around the edge of the plate, to ensure correct re-fitting.

You can't, the sonic screwdriver isn't an actual screwdriver. It's a sonic alien one. ;)

On the show, the sonic screwdriver is basically a torch and makes no sound, they add the sound in later while editing.

Because they are a pain to install with a power bit !-Frankly, now that we have Robertson, Torx and Allen heads, I am flabbergasted that anyone still uses flat heads.

All vehicles have many Allen screws on them. The only sensible and economical thing to do is buy 2 sets of Allen keys, usually 1/32 up to 3/8 in SAE and 1-10mm in metric. They only cost about $ 12 per set and will save you a lot of hassle if working regularly on cars.

I believe that is a 12mm for the bolts and 5/16 for the wiring.

Yes, they can.

You screw them in and maybe later screw them out, I don't see any 'maintenance'

No, a wrench is a wrench

Because sometimes you need to pound things, and that's not good to do with a wrench or screwdriver.

Pliers are used to secure the opening of the stem of the pipet to ensure a tight seal and prevent any leakage of liquids during transfer. This is particularly important when working with volatile or hazardous substances, as it minimizes the risk of contamination or spills. Additionally, using pliers helps maintain consistent pressure on the pipet, allowing for accurate and controlled dispensing of liquids.

None really, you just have to extra careful working near finished surfaces.

I'm sure it's worth a lot to you, but nobody cares about good quality tools any more. There is so much cheap junk on the market, people now would rather buy something cheap and gaudy than a quality made tool.

Screwdriver help people to work fast

It depends on the screwdriver. Only a really little one would weigh 3 ounces...but I guess you could make a great big screwdriver with a real long shank that weighs three pounds.
