What is an 11-in-1 screwdriver?

An 11-in-1 screwdriver has interchangeable parts and functions as 11 different tools in one. 11-in-1 screwdrivers are used by electricians, mechanics and technicians of all kinds. The thicker shaft can sometimes be a hindrance, but the primary benefit of an 11-in-1 screwdriver is obvious: it allows you keep 11 tools on hand while taking up only a small amount of space in your pouch, tool bag or toolbox. Below are the primary parts/functions of an 11-in-1 screwdriver:

  1. 5/16-in. Nut driver
  2. 3/8-in. Nut driver
  3. 3/16-in. Slotted
  4. #1 Phillips
  5. 1/4-in. Nut Driver
  6. 1/4-in. Slotted
  7. #2 Phillips
  8. #2 Square
  9. #1 Square
  10. T10 TORX
  11. T15 TORX

How is an 11-in-1 screwdriver used?

Using an 11-in-1 screwdriver is simple: Figure out which type and size fastener needs to be installed or removed, and then flip the shafts and bits until the appropriate tip is exposed.

What are the different types of 11-in-1 screwdrivers?

Most 11-in-1 screwdrivers have the same nut driver, slotted tip and Phillip tip configuration, but not all 11-in-1 screwdrivers come equipped with TORX and square drive tips. There are many different bit tips available. Some pros keep a variety on hand and swap them out depending on what type of fasteners they’re working with. Also, there are many other combination screwdrivers on the market that carry as many as 26 different bit tips.

What makes a good 11-in-1 screwdriver?

  • Insulated handle
  • Durable but easy to swap bits
  • Comfortable
