The M16 assault rifle's bolt and bolt carrier are made of steel.
Depends on the material used in the bolt, the loading it will be subject to and the environment it will be used in.
To prevent the material that the bolt is being screwed into from giving way, or being damaged. The washer displaces the pressure over a larger area which allows the bolt to still hold, but not damage the material.
For what I read tonight, as I am doing my Big Block, the 4 bolt main is 110LBS

This depends on the manufacturer of the material and what type of material is on the bolt. A bolt is not necessarily a unit of measure for material, it is simply a means of wrapping the fabric neatly for both the transport and sale of the material. A bolt can also only carry a certain amount of weight depending on the strength of the cardboard. Therefore, the amount of material on a bolt can vary greatly. In regards to "how much" meaning "how much does a bolt of material cost" (if this is what is being asked), this also depends greatly on the type of material. Fabric can range in price anywhere from <$1 a yard to >$200 a yard depending on the type.
It can be either a 2 or 4 bolt

Tensile strength is a material propery, it does not depend on size. Look at a material chart to find its yield and tensile strenghts. Then use the stress equation, Stress = Force / Area to determine if your .375 bolt can handle the force on it. If your bolt is in shear, you need to find Shear strenghts.
