it's determined by the hardness (and age, wear, environmental conditions, etc...) of a material. many tests are done by manufacturers to see statistaclly when they will break down.

A grade 5 hex bolt has 3 radial lines formed into the top of the head. Bolt manufacturers can provide listings of bolt markings and their corresponding strength ratings.

It indicates how many staples per strip. S.F. 1 and S.F. 4 are 210 staples/strip. S.F. 3 is 105 staples/strip, i.e. a half strip. Larger staplers take the full strip, smaller ones take the half. The S.F. actually stands for "Stapler Food" which personally I find a little stupid, but that's what it stands for... Also, S.F. 1 are standard-quality staples while S.F. 3 and S.F. 4 staples are premium-quality staples.

Measure the mass (in kilograms) and length (in metres) of the strip. Divide the first by the other.
Gauges to allow a person to calculate nut bolt size are widely available. Measuring the thread manually can be unreliable so it is far preferable to use a gauge.
assuming your bolt is visible, check to make sure that there is atleast something left of the bolt head. If so, sears sells a set of specialized strip sockets by craftsman. some parts stores will Cary IRWIN brand, who also has a good set of strip sockets. these tools are not inexpensive, but do come in handy if you work on your own vehicle.

To effectively remove a hex bolt, use a wrench or socket that fits the bolt size snugly. Apply steady pressure in a counter-clockwise direction to loosen the bolt. If the bolt is stuck, try using penetrating oil or heat to help loosen it. Be careful not to strip the bolt by using the correct size and type of tool.
Torque is not the type of bolt but a type of wrench used to tighten bolts. A torque wrench will tell you how tight a bolt is tightened like 60lb of torque or tighten to 80lb of torque so a bolt will be tight enough to stay in but not too tight that you strip the bolt.

It may gall if it is of the same material as the bolt. It may need to be lubricated, that will prevent this; also, if over-torqued it may gall or strip the thread.
