Screwdriver bit types and sets

Read the marking on the screw or its specification before choosing a bit. PH, PZ, slotted, hex and Torx describe different tip forms, and each family also has sizes. A large piece count is less useful than a clear contents list showing the exact tips you use regularly. Bosch’s accessory tables list tip designation and bit length separately. Compare those details with your holder and available access; a set containing short insert bits may need a separate holder.

MATCH THE DETAILS TO YOUR JOB

What to check before buying

  1. Match both the tip family and size, such as PH2 or PZ2, to the fastener specification.
  2. Check the bit shank, holder connection and overall length against your screwdriver or powered driver.
  3. For an impact driver, require the bit manufacturer’s explicit impact-use specification for the selected range.
  4. Read the quantity of each tip and whether the advertised piece count includes holders or the case.
