The Best Security Bit Sets for Your DIY Projects

two different boxes of security bit sets side by sideJust about every DIY expert will tell you that “use the right tool for the job” is a fundamental principle for home projects and repairs. Tools are precisely designed for a specific purpose, so having the correct tool on hand will make it easier for you to get your job done with less time and effort and without injuring yourself or damaging what you’re working on.

Screws are used in all kinds of products and projects, from woodwork to appliances and automobiles to computers, so an aspiring DIYer will need a good understanding of the various types and the proper tools to use with each screw.

The basic parts of a screw are the head, the non-threaded shank, the threaded shank, and the tip. The head of a screw can be different shapes, like pan, button, or countersunk, and it will also have a screw drive, the system used to turn it. Slotted and Phillips screw heads are the most common types of screw drives used in the United States.

A screwdriver bit is the tool you use for driving screws: the bits you use must fit the head’s drive type tightly so you have sufficient torque to rotate the screw. “Security bits” is the name given to the attachments made for use with drills, screwdrivers, or impact drivers to turn screws that have less common head types like Pozidriv (common in Europe), Allen (aka hex), double hex, or Torx (popular in automobiles, appliances, computers, and electronics).

These are our picks for security bit sets that will give you the right tools for the job.

How to Choose Your Security Bit Set

Consider these basic features when choosing your security bit set:

  • Bit types: The are more than 32 types of screw drives on the market, so make sure the set you choose has the bit types for the screws you’ll be working with.
  • Size: You need a bit size that fills the screw head securely; otherwise, you could strip the screw or damage your bit. There are standard gauge sizes for every type of screw and corresponding bit sizes. Make sure the bit set has the size selection you need.
  • Case and Holder: The type of case can have a big impact on the usefulness of your bit set—it should be sturdy and fit the bits snugly (you don’t want your bits to fall out!), but not so tightly that the bits are hard to remove. Magnetized bit holders can help you fit your bit in the screw head more easily and securely.
