Power tools make it possible to perform many tasks and are great for completing tons of DIY projects. However, your power tools are only as good as the accessories you have to complete those projects.

With hundreds of assorted screwdriver bits and screwdriver bit sets available in stores and online, Ace Hardware makes it easy to get the necessary tools.

Screwdriver Bits: Numbers and Symbols

If you're new to buying screwdriver bits, the numbers and symbols used to describe them may seem like a secret code. Once you understand their meanings, comparing options is simple. Often, bit descriptions include a picture showing the type of screw head. Some of the most common types include:

• Slotted: Slotted screwdriver bits have one slot that cuts across the center of the screw, often used for simple applications requiring minimal torque.
• Phillips: Slots are arranged in a cross shape on these bits, with all four arms equal in length. They’re often used for precision projects as the torque is naturally centered, allowing for a straighter drive.
• Torx: Torx screwdriver bits have star-shaped sockets with six lobes, and they’re often used for tamper-resistant and high-security applications.
• Hex: Hex bits have a six-sided head with no slot. These are commonly used for fastening wood pieces or wood to metal.
• Spanner: Spanner bits have a round head with two drilled holes and are best used for tamper-resistant applications.
• Tri-Wing: Tri-wing screwdriver bits have slots arranged in a Y shape, and they’re often used on electronics.

In addition to the symbol, assorted screwdriver bits also have a number that refers to their size. Screws come in standard sizes, and each type has its own system. No matter what kind of screw you use, the larger the number, the bigger the size. Additionally, screws in an impact driver set are often color-coded for easy reference.

Should I Buy Screwdriver Bit Sets or Individual Bits?

Whether you buy screwdriver bit sets or buy bits individually depends on your needs. If you're new to power tools, purchasing a large impact driver bit set that includes drill bits and screwdriver bits in various sizes can give you the essentials needed to complete many projects. Some sets even include additional accessories like countersink bits and chuck keys.

For a specialty job, it may make more sense to purchase assorted screwdriver bits separately. This is especially true if you'll be working with a type of screw you won’t ever use again. Buying bits individually is also a cost-effective way to replace one broken or bent accessory.
