A carbon based material which is built up from a series of smaller units (monomers). The choice of the monomers and the final molecular weight (i.e. size) of the polymer govern the mechanical and physical properties of the resultant polymer.
Generally a flat piece of material with a threaded hole which can be screwed onto a bolt to fasten items together. Nuts typically have a hexagonal external shape. Nuts are available in metric and inch-threaded sizes.
