What Is a #2 Phillips Screwdriver? | The Cross-Point Workhorse

A #2 Phillips screwdriver is the most common cross-point driver size, designed to fit PH2 screws for general household and assembly work.

For the full breakdown, see our best 2 Phillips Screwdriver guide.

The #2 Phillips, also called PH2, is the size most people reach for first. It fits the cross-shaped recess in countless screws on furniture, appliances, electronics, and light fixtures. Whether you are tightening a cabinet hinge or assembling a flat-pack desk, this tool usually does the job—provided the screw is sized to match.

What Makes It a #2?

The number refers to the tip size under the Phillips sizing system, not the screw’s width. Phillips sizes run from #0 (small) up to #4 (very large), and each tip pairs with screws designed for that range. A #2 or PH2 tip is the middle, general-purpose option that most manufacturers list as the default for everyday work.

The tip’s cross-point shape seats into a matching recess in the screw head. When the fit is right, the driver transfers torque evenly without slipping. When it is wrong, the tip can “cam out” and strip the screw head.

How to Match a #2 Phillips to Your Screw

Select the tip that fully seats in the screw recess with no wobble. A #2 Phillips commonly pairs with wood screws in sizes #5 through #9 and machine screws in metric sizes M3.5, M4, and M5. If the driver rocks or feels loose, switch to a larger or smaller Phillips size rather than forcing it.

Keep the driver straight and in line with the screw. Angling it increases the chance of slippage and damage to both the screw head and the workpiece. Apply firm, steady pressure straight into the screw as you turn.

What a #2 Phillips Is Not

The #2 designation only covers Phillips cross-point tips. It says nothing about flat-blade or slotted drivers, and the two systems are not interchangeable. A common error is treating the number as a blade-width measurement in fractions of an inch, which it is not.

Tool specs also vary between brands even when the tip is the same size. Length, handle grip, magnetic tip, and insulation differ by model. Klein Tools, for example, lists its 603-4 #2 Phillips with a 4-inch shaft and 8.25 inches overall, while the 603-10 stretches to a 10-inch shaft. Both share the same #2 tip but suit different reach and torque needs.

Insulation matters if you work near live circuits. Some Phillips drivers are explicitly insulated to meet electrical safety standards; others are not. Check the product listing before using any screwdriver on energized equipment.

Common Mistakes to Avoid

The fastest way to ruin a screw is reaching for the wrong Phillips size. A #1 tip rocks inside a #2 recess and strips the head under torque. A #3 tip will not seat deeply enough to grip. Both damage the fastener and frustrate the job.

For household and light assembly tasks, the #2 Phillips handles the bulk of what most people encounter. For a closer look at specific models, Klein Tools’ #2 Phillips catalog lists current dimensions and standards compliance side by side.
