The Allen wrench is a bit of a confusing tool because frankly, it doesn't look like any other wrench with its distinct and somewhat bizarre L shape. And since many DIYers don't happen to keep an Allen wrench handy in their toolkits, it's a common problem to find oneself standing around looking for ways to improvise an Allen wrench in a pinch.
Allen wrenches have an L -shape that doesn't match many other tools, which can make it feel immediately a little off-putting. That's why you might find yourself at a bit of a loss when you're looking for ways to improvise an Allen wrench in order to complete a DIY task.
What Is An Allen Wrench?
Allen wrenches are otherwise known as hex keys and they're used specifically on hex screws. Allen wrenches are a registered trademark design created by the Allen Manufacturing Company.
In the battle of Allen wrenches vs. hex keys, there is no battle because they are the same tool. Since Allen wrench is a proprietary name, hex keys are made by other toolmakers that don’t have the rights to the name but create a very similar wrench.
Most Allen wrenches have a flat end that allows the wrench to fit inside a screw head or hut. Some Allen wrenches have a ball-end design that allows you to work on a screw when you're at an angle.
There are many reasons why you might need an Allen wrench...which means that if you don't already have one of these tools, you're going to have to find an Allen wrench substitution for one of these tools. Luckily, there are ways to improvise an Allen wrench when you can’t stop your project to go buy new tools.
How to Improvise an Allen Wrench
Need to know how to remove an Allen screw without an Allen key? What should you do if you don't have an Allen wrench handy to use for the job at hand?
It can be very stressful when you don't have the right tool for the job. And of course, you should always use the tool for the job it's made for…in a perfect world.
After all, you know you shouldn't try to drive a nail into the wall with a screwdriver. But when it comes to Allen wrenches, hex keys, there are some household items and tools you can use instead of this wrench.
You may not know it, but you probably have more than one Allen wrench alternative laying around the house. Because after all, you don’t always have the right tool for the job so sometimes, you have to get a bit creative.
There are some other tools you might have around the house, even if you haven't got an Allen wrench. Torx keys have a very similar L shape to Allen wrenches and clearly can work as an Allen wrench substitute in some cases.
Torque wrenches can also work in a pinch because these tools give you great control over fasteners like screws. They provide a lot of grip, so you can use them in some cases to muscle Allen screws when needed.
Wondering how to use a screwdriver as an Allen wrench? Where is it possible to use a screwdriver on an Allen screw?
Sometimes you can use small types of flathead screwdrivers as a hex wrench by putting the end in the socket so that the two edges of the screwdriver work as leverage in the hole to turn it and loosen the screw. The wider the socket on the bolt or nut, the wider the flathead screwdriver you will want to use.
The objective here is to wedge the screwdriver into the hex of the bolt to create torque so it can be unscrewed. Combination wrenches or open-ended wrenches can give you leverage and grip on screws, so they can be effective at loosening Allen screws when you can't get your hands on an Allen wrench.
Sometimes, you can even use a socket wrench to grip onto an Allen screw and unscrew it or tighten it down as needed. Play around with the different tools you do have available and try out a few different once to find out what's going to work.
You probably have items laying around the house right now that will work beautifully as an Allen wrench alternative in a pinch. If you're working with a small Allen screw, reach for a pair of tweezers.
The flat edges of the tweezers are perfect for smaller Allen screws and the design gives you gripping control even on these smaller screws. It can be a bit awkward to work with tweezers this way but once you get a good grip, you should be able to get the screw loosened or tightened as needed.
You can also find great improvised Allen wrench-type devices in your kitchen cupboard or in the silverware drawers. Flat-tipped and strong paring knives could potentially work, depending on the gauge and depth of the hex screw's hole.
You can even use a coin, sometimes, or two coins to get into the head of an Allen screw and loosen or tighten it. Start looking around with your creative DIY eye and you might find all kinds of little items that work well as an Allen wrench when you're in a hurry.
Nuts and Bolts
Some Allen wrench screws are actually bolts and have a nut on the reverse side. In this case, you can use pliers to remove the nut and it will come free.
If you do not have access to a pair of pliers, then you can use two butter knives as leverage and place them tightly on either side of the nut to create your own Allen wrench substitute. You might need another set of hands when you're using common items like this as a wrench substitute, because the steadier you can keep your work and the improved tools the more control you will have.
Apply pressure and torque on these tools as you spin them about and they can help to work the nut off. If you have a friend helping, they can hold a wedged tool in the hex to keep it from spinning while you turn the nut on the backside.
There are some other, more outside-the-box solutions you can use as an Allen wrench substitute as well. How do you loosen a bolt without an Allen wrench?
How about duct tape? This is the go-to DIY solution for any number of problems, including an Allen screw when there's no Allen wrench around.
Tear a piece of duct tape to make two strips and stick one strip to the back of the screw or nut. Use the other strip to wrap around the tape and pull the duct tape to loosen the fastener.
You can do something similar with a zip tie by tying it around the top of a screw or bolt and creating your own Allen wrench substitute. Use the zip tie to get leverage on the screw and pull on it to loosen and unscrew it.
