Here's a great assortment of the smaller Nylon Screws and Washers. (This set would cost $46.50 at hobby shop prices!)
Many uses in model building (cowl, canopy, landing gear, hatches, etc.). Saves weight compared to steel screws and is gentler on plastic and fiberglass.
A really handy set to have at the building table.
