Our pick: the Bosch 32-piece “Pro” screwdriver bit set, because it covers Phillips, Pozidriv, Torx, hex and slotted screws in one compact case for $36.53 on Amazon.com, rated 4.7/5 from 24,814 ratings (checked October 27, 2026).
Why Phillips and Pozidriv get mixed up
Phillips (PH) and Pozidriv (PZ) share the same cross shape, yet they are two different drives. Pozidriv, patented by GKN in 1962, is an improved Phillips: it adds small extra ribs between the arms of the cross so the bit engages more fully and is less likely to cam out at higher torque (source: Wikipedia, “List of screw drives”). A Phillips bit wobbles in a Pozidriv screw: it holds poorly as soon as torque rises and ends up rounding the recess. The other way round, a Pozidriv bit jams into a Phillips screw and damages it just as surely.
In American hardware stores, most screws you buy are Phillips, deck and construction screws often come with a square drive or a Torx (“star”) drive, and Pozidriv shows up mostly on furniture and hardware made in Europe. That’s exactly where stripped screws come from: the habit that ruins the most screws isn’t a bad clutch setting, it’s a “cross-head” bit that is neither truly PH nor truly PZ. This guide sits in our Drilling & Driving section.
How to identify a screw head in 10 seconds
No magnifier, no spec sheet; four clues are enough:
- Phillips (PH): a simple cross, smooth arms, nothing in between.
- Pozidriv (PZ): a cross with a small extra notch between each arm, eight lines in all when you look closely.
- Torx (T or TX): a six-point star with rounded lobes, developed in 1967 by Camcar Textron. It looks like neither of the crosses and slips much less under high torque, which explains its growing place on deck screws, appliances and premium furniture.
- Square (SQ, also called Robertson): a square socket, very common on US deck and cabinet screws. Any good set should include it.
The size stamped on the bit (PH2, PZ2, T20, SQ2…) remains the most reliable reference when you can read it: the number gives the size, the letters give the type.

25 one-inch bits, nine 2-1/4 in. bits, a 3-1/2 in. bit, two nut drivers, a magnetic bit holder and a socket adapter, per DeWalt. The FlexTorq zone absorbs the peaks of an impact driver so the bit doesn’t snap: the pick if you drive a lot of deck or framing screws. Sold by Amazon.com, and the number-one seller in screwdriver bit sets that day.

If every screw in your house is Phillips and square, and you never assemble European furniture, you don’t need Pozidriv bits: the DeWalt 40-piece set covers you for less. For the tool that drives these bits, see our best cordless drill comparison.
How Malin chooses
Malin: “I never look at the piece count first. A 200-bit set with 40 Torx sizes you’ll never use doesn’t help more than a well-spread 30-piece set. I check three things: that Phillips, Pozidriv and Torx are all there, that the sizes are engraved (not just printed, which wears off), and that the steel is announced as S2 or equivalent, otherwise the bit twists before the screw does.”
Method: we did not test these sets ourselves. Specs come from the manufacturers and the Amazon.com listings, prices and ratings were read on October 27, 2026, and the drive history comes from the Wikipedia pages listed below.
Frequently asked questions
Can you use a Phillips bit on a Pozidriv screw?
It “fits” visually, but the bit has play in the Pozidriv recess. On a short screw at low torque, it may work once; as soon as torque rises (impact driver, long screw), the bit slips and rounds the recess, and the screw becomes hard to back out.
How can I tell Phillips from Pozidriv without removing the screw?
Look closely at the recess under raking light: if you see eight lines (four big arms and four small offset notches), it’s Pozidriv. A simple four-arm cross with nothing in between is Phillips.
Why is Torx showing up on more screws?
Because it slips much less under high torque than cross-shaped drives, which lowers the risk of stripping the screw or marring the panel around it when you drive with a power tool. Many deck and construction screws sold in the US now use a Torx (“star”) drive.
Do I need special bits for an impact driver?
Not strictly, but regular bits wear out faster under an impact driver’s blows. A set sold as “impact ready” or with a torsion zone, like the DeWalt FlexTorq 40-piece at $17.98 on Amazon.com (October 27, 2026), lasts noticeably longer for that job. Our impact driver vs drill guide explains when each tool makes sense.
Does one bit size fit every screw of the same type?
No: the number matches a range of screw sizes. Per Wikipedia, a #2 Phillips driver fits #5 to #9 wood screws; a smaller or bigger screw needs a #1 or a #3. The same logic applies to PZ1, PZ2 and PZ3, even though they are all Pozidriv.
Our verdict
For everyday home use (furniture, shelves, small repairs), the Bosch 32-piece “Pro” set at $36.53 covers Phillips, Pozidriv and Torx in one case, at a price that makes it easy to keep one in every toolbox. If you drive a lot with an impact driver (deck, framing), the DeWalt FlexTorq 40-piece at $17.98 earns its place with longer life under impacts, and 48,092 ratings back it up. Either way, the rule that saves the most screws stays the same: read the marking before you push, and your next screw will go in clean.
