Reuben's Quick Tip: How To Make A Better Allen Wrench

Allen wrenches, aka 'hex' wrenches, are those "L" shaped wrenches that come included with just about anything you buy from IKEA.  I save these wrenches every time I get one, and I've accumulated a nice little hodge-podge collection of wrenches over the years.

To make sure you always have the size you need, it's a good idea to get a folding wrench set with all of the sizes built in - both metric and standard.  I consider this a must-have for any basic tool set.  I have two wrenches, one for metric and one for standard.

Allen wrenches

One day, my wife and I were putting something together that needed a lot of allen wrench turning, and I started telling her about how I should buy a set of allen wrenches that have socket wrench ends on 'em, like the set pictured below.

My wife then suggested I just cut the end off one of the "L" shaped allen wrenches and stick it in my drill.


I could have thought of that.

I just didn't want to.

It took me about 30 seconds to cut the end off and file it down, turning the L shaped allen wrench in to a hexagonal stick that I could put in my cordless drill.

The assembly project we were working on went much faster after that.  I was so happy with this 'invention' that I made a full set out of my spare wrenches.  I drilled a bunch of holes in a block of wood to store my wrenches in.  It's probably not the best way to store them, but it was the first thing I thought of and it's worked fine for me ever since.

Now go forth and make your own set.  Just for fun, here's a video of me demonstrating how to make your own set, along with some questionable relationship advice.

Wait a minute, you recommend gloves but don't wear them (but it kind of made me proud to see you didn't)?

Is your set American or metric?

I have an Allen wrench set for my bike, emergency tool kit, car tool kit, a couple of other tool kits, and in both of my drill kits.

I didn't make my own however!

Did monkeys invent the Allen wrench?

And is that how Swedes or Minnesotans spell GENIUS?

Ha!  I said you could use a bunch of protective gear.  I suppose I should have been using eye protection, but I have these built-in sacrificial lenses that I keep in my eyes at all times.  

I have two sets there - American and metric.

It sounds like you could use another set of allen wrenches for each bathroom, Jay.  I think that's the only thing missing on your list.

The monkeys have their very own wrench :)

What's the most important Allen wrench for a home???  The one that unbinds the garbage disposer. 

Guess what was missing in the kitchen of a new home pre-settlement walk-through yesterday?? 

The garbage disposer Allen wrench.

In the ooooolden days, disposals did not come with the Allen wrench and the way to unstop them was with a broom handle from above!

Great idea.  I'm going to suggest to my husband and look wicked smaaht.

Jay - is that how you're supposed to spell it?  I got that shirt from a friend who lives in Virginia.  I've done my share of the 'broom handle' method during inspections when I didn't want to get my allen wrench set. 

Lenn - good point.  I ought to start carrying one of those around in my tool pouch just for those instances.  

You look for those garbage disposer wrenches?  Good for you!

Barbara - he better give you credit ;)

This does have some merit....can't recall the number of hours spent looking for the right allen wrench.  I have so many! It seems like they reproduce!

That's what we used to call Yankee ingenuity!  Waste not, want not.  Having said that, the advantage of socket sets is that you can get a lot more leverage out of them when needed.

Indeed I look for that wrench. I'm convinced that new home builders have a huge repository where they collect Allen wrenches from new homes and sell them on e-Bay.

I also check the size of the disposer motor so that, unless a large one was installed, the disposer WILL jam and bind and the wrench is often the only thing that will release the motor. 

Builders won't say to a buyer "This is a small motor, so expect it to bind". 

I'll tell them.  That's my job.

It's a little thing, but. . . . .

Reuben, That's quite the tool collection you've got there!  Not every day I see someone with a gear puller as part of their collection.  Bill

I have the coveted allen wrench collection from Ikea and other places and I have the Lenn Harley special wrench that frees the disposal everytime...I am wrenched up and ready to go here

Reuben, now that'a a good idea. Kudos to your wife. You've got quite a workshop. Thanks.

I hate the wrenches that come out of the bag with a socket set and they're all sticky with some foreign non-washable substance on them. At least your set is clean and easy to make.

Reuben, I think your wife and I went to different schools together :)  Here is another trick for you (of course pretty much useless in this day and age of nail guns) When you have to drive a finish nail and you don't want to split the wood---just take another nail like the one you want to drive---stick it in your screw driver (just like your allan wrench) and drill a hole with the nail---and then drive and set your finish nail.

Just make sure you use a multi speed drill. .. or your invention will round the hex out of a nut! (never thought I would ever say that)

That's a good tip and have done it myself several times. I also like cutting the head off a nail and using it for a drill bit in a pinch.

As a tool freak myself, I found this article rather interesting.  Thanks for the post!

Now what to do with all those tiny wrenches they include that disintegrate after one use?  Heh, heh~!  Yes, I have a least one metric set in the tool box, and a handful of non-IKEA specials.  I do have that problem with slippage when I put the allen wrenches in the drill sometimes.

What article?  I was too busy looking at all the tools, especially the last photo of the complete workshop AND TOOLS!  I'll go back and read the articel now...

Confess now if you have ever used an Allen wrench in a Torx-headed screw (successful on rare occassions)!

Posted by Jim Gilbert, The Gold Homes Team (Keller Williams Fairfax Gateway) over 6 years ago

I have a tool with lots and lots of different sizes of Allen wrenches that fold out from each end. Your wife is a smart lady.

Good tip Reuben. If I only had an awesome workshop setup like yours, then I could make my own! Youre wife gets points for the idea, you get points for's a tie!


p.s. can you please wear goggles next time?

That sure looks better than the messy tool drawer in my tool box!   Thanks for the great idea.

Your power drill/driver has the power to twist those 'hand tool' components into pretzels of junk or strip out the socket of what you are trying to loosen.

A variable speed control works best. Wear eye protection.
