All adults should have screwdrivers in their tool box.
There are several types of screwdrivers.
🔨 Standard / Slotted Screwdriver (“flathead”)
There are several sizes of standard screwdrivers (commonly referred to as flathead screwdrivers). A set of standard screwdrivers contains several different sizes. It is generally a good idea to have a set of standard screwdrivers in your tool box.
🔨 Phillips Screwdriver
A Phillips screwdriver looks like a modified X. It is generally a good idea to have at least a #1, a #2, and a #3 Phillips screwdriver in your tool box. If you wear glasses, a precision screwdriver set will contain what you need to make minor repairs.
🔨🛠Allen Screwdrivers / Allen Wrenches
The Allen type screwdriver, also called an Allen wrench, is a common one to have if you build a lot of IKEA furniture. The IKEA box generally contains one, but if you want to add a set to your tool box, it’s not a bad idea, especially if you’re a homeowner.
Aside from these three types, there are others that fall into the category of “unless you’re doing something really specialized, you won’t need one of these.” Here are just some of the more esoteric screwdriver types you might find, along with what they are called.
