The basic design remains unchanged. A 15th century craftsman wouldn't have any problems driving a 21st century screw. On the other hand, the science and technology behind this seemingly simple fastener could fill libraries.
One of the most significant changes centers on the creation of production screws, fasteners manufactured for specific tasks.
Considering that the varieties number in the hundreds of thousands, it's easy to feel overwhelmed. The way to handle the info overload is to face the facts: production screws are made for production, not necessarily small-shop woodworkers. But that doesn't mean you can't benefit from a trickle-down technology.
You don't need a store-sized collection of fasteners or an engineering degree to get the job done right. What you need is the knowledge to pick and choose a manageable screw assortment for handling most woodworking tasks, plus a few specialty fasteners to tackle specific applications.
