Reviews

Well, the screws are PERFECT! Heads have the proper indentations for Phillips screwdrivers, threads evenly spiraled. Really, tho, the service at Aircraft Spruce is GREAT! I have been doing business with them since 1979 or 1980, and they are always providing great service and proper invoicing. Couldnt have built nine experimental aircraft without them.
