How to use a ratchet screwdriver without rounding the screw

Updated: 23 October 2026

The handle clicks the wrong way, the bit climbs out of the head, and a Pozidriv screw that was fine a minute ago is now a round hole. How to use a ratchet screwdriver is mostly three checks made before you lean on it: the ring, the recess, and the moment you stop. This page from the Products Compared editorial team, 22 October 2026, assumes the tool is already in your hand. It covers the Bosch pop-up ratchets and the Wera magazine handles in our [Magazine screwdriver comparison](/hub/hand-tools/magazine-screwdriver). There are no prices here.

Set the ring before the screw

On the Bosch bullets the metal ring has three positions: left, right, and a middle setting for manual use. Wera’s wording on the RA 2 is to turn the switch the way you want the screw to go. Position 0 locks the mechanism. Clockwise tightens a normal right-hand screw. Anticlockwise undoes it. Do not hunt for a tab on these handles. Check it in the air. Magazines 1 to 4 have no ring. The Kompakt 20 and the 27 XL do not claim a ratchet either. Use the middle or position 0 for the last tighten, then stop if the screw still refuses.

Choose and seat the bit

Match the recess before you worry about the magnet. UK wood screws are commonly Pozidriv. A Phillips bit can cam out of that head. The Bosch 12-bit lists PZ sizes and no Phillips. Wera magazine 2 lists both. Push the bit fully into the 1/4 inch hex until it stops. Bosch quotes an 8 N magnet, a listing claim, not a pull we measured. On a Bosch pop-up, take one bit and close the magazine before you drive. On a Wera stubby, swivel to the tip. A store that will not stay shut is a parts problem.

Turn, then stop

Short strokes, with the ring set, are what the click is for. Keep the bit in the recess and let the handle return without lifting the tip. The moment the bit climbs out, stop. HSE guidance is plain: do not keep loading a handle that digs into the palm. Do not hammer the handle or add pliers. A circuit you cannot prove is dead is not practice. Regulation 14 still means isolate first. One Bosch 12-bit review reports a tip snapping. If the head is smooth, replace the screw.

When the store itself is the problem

Sometimes the screw is fine and the handle is not. UK reviews of the Wiha say the top opens on its own or that clips fell off. The Kompakt 28 reviews include bits leaving the holder. If you are hunting for a direction ring on magazine 2, you have a fixed stubby. Put the tool down when the store will not close, when the bit will not stay seated, or when the ring will not hold a detent.

Common questions

Which way do I turn the ring to tighten a normal screw?
Clockwise, so the shaft drives clockwise, for a normal right-hand screw. Wera’s RA sheets say to turn the switch the way the screw should go. Bosch’s bullets call the same control a metal ring with left, right, and a middle manual setting. Feel it in the air first. If the handle freewheels while you try to tighten, the ring is on the undo side or sitting between positions. The non-ratchet Wera stubbies have no ring to set.
What is the middle or 0 position for?
It locks the ratchet so the shaft and the handle turn together. A UK review of the Bosch stubby says the middle position works like a normal screwdriver. Wera calls the locked spot position 0. Use it for the last tighten, and when a screw may be seized and you do not want the pawls to slip. It does not add length or leverage. If the screw still will not move, stop rather than forcing a handle into your palm.
How do I change a bit without dropping the set?
On a Bosch pop-up, open the magazine, take one bit, and close it before you drive. On a Wera captive stubby, swivel the magazine to the tip you need instead of pulling the store apart. Push the bit fully into the 1/4 inch hex. If bits are already falling out, as one Kompakt 28 reviewer described, fix the holder before you start on a visible screw. A Wiha cap that opens in a pocket is a fault in the store, not a step you can tighten your way past.
Why does the bit jump out of the screw?
Usually because it is the wrong recess, or because you are lifting off the head. A Phillips bit in a Pozidriv screw cams out once the screw bites. A bit that is only half-seated in the socket rocks. Bosch quotes 8 N for the magnet, and that claim will not keep a mismatched tip in a chewed head. Push along the screw. When the bit climbs, stop. Another turn on a cammed recess rounds it.
Should I hit the handle if the screw will not move?
No. Do not hammer the handle, and do not grip it with pliers. Lock the ratchet or change to a longer fixed driver, and make one controlled effort. HSE guidance is to stop when the handle digs into the palm. A seized screw in heavy timber is the wrong job for a 65 mm stubby. Gas fittings, and any circuit you cannot prove is dead, are the point where a competent person takes over.
