How to Use a Power Screwdriver | Drive Screws Right Every Time

For the full breakdown, see our best Electric Precision Screwdriver guide.

Most stripped screws and damaged workpieces aren’t the tool’s fault — they’re technique failures. The difference between a clean drive and a cam-out that ruins the screw head comes down to a few repeatable habits. Here’s the exact sequence that works on corded, cordless, and push-to-start electric screwdrivers.

What You Need Before You Start

Get the basics right before pulling the trigger. First, pick the correct bit for the screw head and size. An ill-fitting bit slips and can cam out, which strips the screw and can damage the work surface. Insert the bit fully into the chuck or bit holder and lock it in — a loose bit wobbles under load and chews up the screw head.

Second, think about torque. If the tool has an adjustment collar, set it low at first. Clockwise increases torque; counterclockwise decreases it. Start low and dial up only as needed. This prevents over-tightening and stripping, especially on softer materials.

Finally, prep the workpiece. Secure it with a clamp so it can’t spin or shift when the screw seats. Use a pilot hole for harder woods or larger screws — this reduces splitting and gives the bit a clean path, which cuts down on slip.

The Correct Driving Technique

Position the screw in the target spot and align the driver straight with the screw axis before starting. Angling the tool even slightly makes the bit ride up the head and slip. Seat the bit firmly in the screw head, then apply steady forward pressure in line with the screw axis while you pull the trigger. For Phillips screws, use extra axial pressure to reduce cam-out.

Drive at a controlled speed and stop when the screw sits flush or reaches the desired depth. Don’t overdrive — once the head bites into the surface, continuing to run the tool simply strips it. If you feel the bit slipping or see the head starting to burr, stop and reassess rather than forcing it.

When you need to remove a screw, release the trigger, switch the tool to reverse, then apply controlled pressure as it backs out. Keep the bit seated and aligned on the way out, just as you did on the way in.

Safety Rules That Prevent Injury

Electric screwdrivers spin fast enough to punish carelessness, and the most common injury is a slip that sends the bit into a finger or hand. The rules are simple. Wear safety goggles — screws can snap, bits can break, and debris flies. Keep both hands behind the tip area; never place a hand in front of or alongside the blade, because a slip can cause injury.

Secure the workpiece before you start, and avoid loose clothing or jewelry that could catch in the spinning tool. If you’re working on a ladder or in tight quarters, take the extra second to stabilize yourself before driving. A controlled tool in a stable stance is a safe tool.

Common Mistakes and How to Avoid Them

The errors that ruin screws and frustrate DIYers follow the same patterns every time. First, using the wrong bit size or head type. A #2 Phillips bit in a #1 screw head is a recipe for cam-out. Second, failing to keep the bit aligned with the screw axis — any angle invites slippage. Third, not applying enough axial pressure, especially on Phillips screws. Fourth, starting with excessive torque instead of dialing it in gradually. And fifth, forgetting to switch to reverse before attempting removal; trying to back a screw out in forward mode just buries it deeper.

FAQs

Can I use a power screwdriver on drywall?

Yes, but only with a drywall bit and a low torque setting. Drywall screws are designed to be driven just below the paper surface without breaking it. Over-torquing with a power driver is the most common cause of torn paper and crushed board. Set the clutch low and adjust upward only if you need more depth.

How do I stop the bit from slipping out of the screw?

Two causes: the wrong bit size, or insufficient axial pressure. The bit must fit the screw head snugly with no play. Then press firmly along the screw axis while driving. If the bit still rides up, the screw head may already be deformed — swap in a fresh screw or use a screw extractor instead of forcing it.

Is a brushless motor worth the extra cost?

For regular use, yes. Brushless motors run cooler, draw less current from the battery, and have no brushes to wear out, which extends tool life. For occasional household tasks, a brushed motor is perfectly adequate and costs less. The choice comes down to how often you drive screws and whether you need maximum runtime per charge.
