How do you stop a screwdriver from camming out?

Push harder before you twist harder. Cup the end of the handle in your palm and press straight down the shank as resistance builds. Use the right size tip, keep the driver in line with the screw, and add a wrench on the handle's flats if your wrist runs out.

Can you put a wrench on a screwdriver handle?

Yes, if the handle has real flats or the driver has a hex bolster near the shank. Keep palm pressure on the end while you turn the wrench in short arcs. Don't do it on round or rubber-grip handles, and go easy on small or brass screws.

What is the end of a screwdriver handle called?

The rounded butt end is often called the pommel. On a classic cabinet-style driver it's domed so it sits comfortably in your palm, letting you push straight down while you turn.

Why is a screwdriver handle shaped like that?

Pick up an old cabinet-style screwdriver, the kind with the hard plastic handle. Skinny neck. Fat round butt. Flat sides. Most of us grab the middle and twist, and never think about any of it. Rex Krueger did. Every one of those shapes is a different grip for a different moment in driving a screw.

⚡ Rule of thumb

A classic screwdriver handle has three working zones: spin the narrow neck with your fingertips for fast run-down, cup the rounded pommel in your palm to push hard and keep the tip seated, and put a wrench on the handle's flats when a screw needs more torque than your wrist can give.

Starting point

Fingertips on the neck while the screw runs free · palm on the pommel once it resists · wrench on the flats for the last stubborn turn

Measured

Neck = narrow section just above the shank · pommel = rounded butt end · flats = the faceted sides of the handle

Applies to

Process: Driving and removing screws by hand
Fasteners: Wood screws and machine screws, slotted or Phillips
Tool: Traditional cabinet-style screwdriver with a flatted handle and a domed end; a wrench that fits the flats
Orientation: Driver in line with the screw axis

Why it matters

Most stripped screw heads happen at one moment: when the screw starts to resist and you twist harder without pushing harder. The tip rides up out of the slot, cams out, and chews the head. Once it's chewed, it's a different job.

The handle is built around that moment.

While the screw spins freely, you don't need force. You need speed. The skinny neck is small enough to roll between your fingertips, so the screw runs down in a few quick flicks.

When it starts to bite, the pommel takes over. It's round so it sits in your palm, and your whole arm can push straight down the shank. Pressure first. That's what keeps the tip in the head.

And when your wrist runs out, the flats take a wrench. Now you've got real leverage, and your palm is still on the pommel pushing down. Rex Krueger puts all three in under a minute.

What good looks like

How to apply it

Start the screw and spin the driver by the narrow neck with your fingertips while it turns freely.
When it starts to resist, cup the domed pommel in your palm and press straight down along the shank while you turn.
If it still won't turn, keep the palm pressure on and fit a wrench over the flats on the handle.
Turn the wrench in short, controlled arcs, keeping the driver square to the screw.
Backing a screw out, do it in reverse: pommel pressure and wrench to break it loose, then fingertips on the neck to spin it out.

Test it on your setup

Drive two identical screws into hardwood. Turn one only by gripping the middle of the handle. Drive the other neck, then pommel, then wrench. Compare the effort and look at the two heads afterwards.
Try a screw that's already a bit stuck. Twist it by hand first and feel the tip want to ride out. Then lean on the pommel and turn again.

Exceptions & tradeoffs

Not every handle wants a wrench on it. Round, rubber-grip and cushioned handles crush or slip. Only put a wrench on a handle with real flats, or on a driver with a hex bolster at the base of the shank.

A wrench multiplies torque fast. Small screws and brass screws snap before you feel them go. Save the wrench for bigger fasteners, or for the one stubborn turn.

Mind you, the shape is doing the work here. A modern ergonomic grip is great for an hour of twisting but often gives up the skinny neck and the flats entirely. If you drive a lot of screws by hand, it's worth owning one of the old-style drivers.
