If you’ve ever stood in front of a loose sign, wobbly bracket, or old lock and stared at a strange screw you can’t turn, you’re not alone. Those are “one-way” screws, and without the right one way screw remover, they can feel impossible to move.
The good news is you can get them out safely, even with simple tools you might already own. In this guide, we’ll walk through what works, what doesn’t, and how to remove these stubborn fixings without tearing up your wall, door, or frame.
By the end, you’ll know which one way screw remover to choose, how to use it step by step, and what to do differently next time so you don’t get stuck like this again.
Quick Answer: The Best one way screw remover Options
Most people want a simple, clear answer first:
The best tools to remove one-way screws are:
- A purpose-made one way screw remover bit or socket
- A screw extractor kit (drill-out type)
- Locking pliers (like Vise-Grips) for grabbing the screw head
- A rotary tool or hacksaw to cut a new slot for a flat screwdriver
In many cases, a basic one way screw remover kit and a drill will do the job quickly, especially if the screw head isn’t too damaged. If the head is worn or painted over, you may need to move up to extractor bits or cutting a new slot.
What Are One-Way Screws and Why Are They Used?
One-way screws are security fasteners that tighten in one direction, but are very hard to turn back the other way. The head is shaped so a normal screwdriver will grip when turning clockwise, but slips when you try to turn anti-clockwise.
They’re often used in public areas, on bathroom fixtures, signs, handrails, or fittings outside, where people don’t want casual tampering. You’ll also find them near security bolts, door hardware, and sometimes alongside Concrete Screws in masonry work.
The idea is simple: easy to put in with the right driver, hard to get out without a special one way screw remover or a bit of know-how.
What Is a one way screw remover and When Do You Need One?
A one way screw remover is any tool or bit designed to grip and turn a one-way screw head backwards so you can loosen it. It usually works by:
- Biting into the damaged or sloped head
- Creating a new gripping surface
- Or drilling into the screw and turning it out
You’ll need a one way screw remover when:
- You’re replacing old fixtures fitted with security fasteners
- You need to remove a bracket, lock, or rail fixed to brick with Concrete Screws and one-way heads
- You’re doing repairs after someone installed security bolts or one-way screws years ago and left no instructions
Before You Start: Safety and Setup
Get Ready Before Using Any one way screw remover
Before you touch the screw, spend a minute setting up. It can save a lot of time and prevent damage.
- Wear safety glasses – especially if you’ll be drilling or cutting a new slot.
- Clear the area – move cables, pipes, and anything flammable out of the way.
- Support the object – if you’re removing a sign, bracket, or lock, hold it so it doesn’t fall when the last screw comes out.
A calm, careful start makes every one way screw remover method safer and more effective.
one way screw remover Options You Might Already Own
1. Locking pliers (Vise-Grips)
If the head of the screw sticks out even a little, locking pliers can often act as a simple one way screw remover.
- Clamp the jaws tightly around the screw head.
- Wiggle a little to break any paint or rust.
- Turn slowly anti-clockwise while keeping strong pressure.
This is a gentle method and works well on softer metals or old fittings where you don’t want to cause more damage.
2. Flat or Phillips screwdriver plus a hammer
Sometimes you can turn the one-way screw by “re-shaping” the head.
- Place the screwdriver at the edge of the slot.
- Tap it gently with a hammer so it bites in at a slight angle.
- Try to twist the screw anti-clockwise while keeping pressure downwards.
It’s not a perfect one way screw remover, but it can work when the screw isn’t too tight and you want to avoid drilling.

3. Screw extractor kit
A screw extractor kit is one of the most reliable ways to remove stubborn one-way screws, Concrete Screws, and even some security bolts.
A typical kit has:
- A drill bit to make a pilot hole
- A tapered extractor with reverse threads
Basic steps:
- Drill a small, centred hole into the top of the screw.
- Insert the extractor and turn anti-clockwise (usually with a tap wrench or drill in reverse).
- The extractor bites into the screw and turns it out.
A good quality extractor is a very effective one way screw remover when the head is too damaged to grip.
4. Dedicated one-way screw removal sockets
There are special sockets made just for this job. They have sharp internal ridges that bite into the sloped head when turned in reverse.
To use:
- Place the socket over the screw head.
- Apply firm pressure and turn anti-clockwise with a ratchet.
These tools are designed exactly as a one way screw remover, so they’re often the cleanest and fastest option if you can match the size to your screw.
5. Rotary tool or hacksaw to cut a new slot
If other methods fail, you can turn almost any one-way screw into a standard slotted screw.
- Use a thin cutting disc on a rotary tool, or a small hacksaw.
- Cut a straight slot across the top of the screw head.
- Insert a flat screwdriver into the new slot and turn slowly.
This is a “last choice” one way screw remover method because it creates dust and sparks, and you can slip and mark the surface. But when done carefully, it works very well.
Step-by-Step: How to Remove a One-Way Screw
Method 1: Start gentle with pliers
- Clean the head of the screw with a cloth to remove paint and dust.
- Clamp locking pliers around the screw head as tight as you can.
- Turn slowly anti-clockwise, keeping a steady grip and pressure.
- Once it moves a little, keep turning until it backs out fully.
Method 2: Use a screw extractor one way screw remover
- Pick a drill bit that matches the extractor size recommended in the kit.
- Drill a shallow pilot hole in the centre of the screw head (go slowly).
- Insert the extractor, tap it in lightly if needed.
- Turn anti-clockwise with a wrench or drill in reverse until the screw loosens.
Method 3: Cut a slot and use a flat screwdriver
- Mask around the screw with tape to protect the surface.
- Carefully cut a slot across the head with a rotary tool or hacksaw.
- Insert a strong flat-head screwdriver into the slot.
- Turn slowly anti-clockwise; press down firmly to stop it slipping.
With patience, each of these can act as a highly effective one way screw remover, even on older fittings.
Dealing with Concrete Screws and security bolts
When one-way screws are fixed into masonry as Concrete Screws or paired with security bolts, things can feel even tougher. The base is solid and often doesn’t give at all.
Tips for these cases:
- Use a drill with masonry bits sized correctly for Concrete Screws if you decide to drill out the whole screw.
- With security bolts, check if there’s a removable nut or shield on the back before attacking the head.
- Combine a strong one way screw remover (like an extractor kit) with slow drilling to avoid overheating the bit or cracking the surrounding material.
Take your time here – bricks and concrete are much harder to “fix” if damaged, compared with wood or plasterboard.
How to Avoid This Problem Next Time
Once you finally get that screw out, it’s tempting to celebrate and forget about it. But it’s worth spending a minute thinking about the replacement.
- Swap one-way screws for normal screws or Concrete Screws with a standard head.
- If you need security, use removable security bolts or tamper-resistant screws that can still be undone with a special key.
- Keep a small one way screw remover kit in your toolbox so you’re never stuck again.
Planning ahead turns this from a frustrating job into a simple task next time something needs fixing.
Conclusion
Removing one-way screws can feel like a battle, but with the right one way screw remover and a calm, step-by-step approach, you can win every time. Start with gentle methods like locking pliers, then move up to extractor kits or cutting a new slot if needed.
Remember to stay safe, protect the surrounding surface, and choose better replacement fixings so you don’t end up here again. A few simple tools and a bit of patience are usually all it takes to turn a “no way” screw into a solved problem.
