A decimeter is equivalent to 10 centimeters, or one-tenth of a meter. This is about 3.9 inches, which can be the size of a large bolt or screw.
There is no advantage whether the handle is 1.2 cm or 10 cm, the screw will still only make one revolution. The reason being is that both the screw driver and the screw become part of the whole. The only increase in the screws revolutions is if the screw driver is geared to make more than one turn of the screw.

I drill a pilot hole the size of the 'barrel' of the screw. -I always use a combination drill bit for sinking screwheads. The first part of the bit is the diameter of the 'barrel' of the screw and the step, one inch higher is the size of that screw's head. (The barrel is the diameter inside threads) -I have a set of these drill bits for #6, #8, and #10 screws and they are great.
It really depends on the material you are drilling. Thinner material will use a smaller pre-drill bit. Try drilling a sample hole on a piece of scrap or where it will not be visible Then try your screw. Adjust your hole size if necessary
You need to find out the size of drill bit you need - put the screw into a screw-bit rack and (going from the smallest to largest), the first one it fits in will be the right bitThen rill the hole, using a scrap piece of material (if appropriate)Then countersink the holeFinally, fitHope this helped, I've got to do this for DT homework
10 mm would be ideal. But 13/32" will work.
The weight of a screw can vary depending on its size and material. On average, a typical metal screw can range from a few grams to about 10 grams.
A number 40 is 2.489 mm, or almost 1/10 of an inch.
3/32"
You can get a really good power tool bundle at sears.com, They have a drill, router, and a 10 peice screw driver bit set for $120. That is a good deal for such a good long lasting drill.
Take it to a gunsmith. There is a tool called an E-Z-out- looks like a coarse thread drill bit, with LEFT handed threads. The smith will use a milling machine to bore into the center of the screw, and use the E-Z-Out to remove the screw.
if you can remove the broken studs without doing damage, you may be able to redrill the holes with the proper tap drill, and retap the hole for the screw in studs without removing the heads. careful you don't drill through the head, and get drill chips in the engine. i guess it depends on how good you do machine work.
The mass of a screw can vary depending on its size, material, and design. Generally, screws are lightweight and range from a few grams to a few ounces. For example, a typical wood screw may weigh around 10-20 grams.
