.... Acrylics do not require specifically designed screws. A general-purpose screw with a length-to-diameter ratio of 16 to 1 or more is satisfactory. A compression ratio between 2-to-1 and 3-to-1 is best. Acrylics are hygroscopic and generally should be dried before processing. In the less humid months...
