Screwdriver Bits

A screwdriver bit is an interchangeable end that fits into a ratchet screwdriver or drill and is used for tightening or loosening the appropriate fastener head type, such as Phillips, flat-head/slotted, Torx or Pozidriv screws.

Frequently Asked Questions about Screwdriver Bits

What is the purpose of different lengths of screwdriver bits?

Screwdriver bits come in varying lengths to provide better reach or precision. Longer bits are ideal for accessing screws in deep or tight spaces, while shorter bits offer better control and stability.

How do I know if a bit is compatible with my power tool?

Check the shank type and size. Most bits have a 1/4 inch hex shank, which fits standard drill chucks and bit holders.

Can impact-rated bits be used with regular drills?

Yes, impact-rated bits can be used with standard drills, but they are specifically designed to handle the higher torque of impact drivers, making them more durable.

What is the difference between standard and security Torx bits?

Standard Torx bits have a simple star shape, while security Torx bits include a pin in the center, which requires a matching bit for tamper-resistant screws.

Why do some screwdriver bits have colour-coded bands?

Colour-coded bands help quickly identify bit types and sizes, improving efficiency on tasks that involve switching between different screws.

How do I prevent screwdriver bits from stripping screws?

Ensure the bit matches the screw head perfectly and apply steady, even pressure while turning. Using a torque-limited driver can also help prevent over-tightening.

Can screwdriver bits be used for both manual and powered screwdrivers?

Yes, most bits are compatible with both manual handles and power tools like drills and electric screwdrivers, provided they fit the chuck or bit holder. This makes them versatile for various tasks.

Do screwdriver bits wear out over time?

Yes, frequent use or using excessive torque can dull or round off the tips. Replace worn bits to maintain efficiency and avoid damaging screws or slipping during use.
