Full Answer

Henry F. Phillips is responsible for inventing the Phillips screwdriver in the 1930s. His intention with this invention was to make it easier to slip a screw out of a recess or cam it out of a recess through the application of excessive torque. This works to prevent machines and laborers from making fasteners too tight. Modern Phillips screwdrivers prevent the stripping of screw heads when coming out because this was a flaw in the original design. Today, there are both screwdrivers and drill bits with the Phillips head.

    What is the difference between enamel and acrylic?

    A:

    Enamel paint is a high-gloss oil-based paint that is typically used on hard, non-porous surfaces such as metal, whereas acrylic paint is a chemical-based paint that is best used on porous and outdoor surfaces due to its ability to expand and contract with rising and falling temperatures. Emulsified polymers give acrylic paint its flexibility. These flexible bonds make acrylic paint ideal for painting on non-porous surfaces as well as porous, because air is what allows the polymers in the paint to maintain their bonds.

    What is the function of a screwdriver?

    A:
