Especially when taking stuff apart, you often come across screws that you just don't have the right driver for at hand. You could always borrow/buy/order a proper tool somewhere, but that takes time and possibly money. When those two are not available in sufficient quantities (or you're just impatient/bored/like to make stuff), then you might consider crafting the necessary tool yourself. In this Instructable, I demonstrate how to make a #6 Torx and a 1.3mm Allen key from wire, using just a triangular file.

Step 1: The Set-Up

The need first arose when a friend called me up late one evening in dire need of a 5 point Torx screwdriver. He'd had a bit of a beverage related incident with his Macbook Pro (Unibody, aka no removable parts). To prevent further damage, he wanted to unplug the battery and remove the mainboard to check for spillage there. Now you can easily remove the back plate of the Macbook with a Phillips driver, everything inside is held in place by the battery, which in turn is fastened by the aforementioned odd-toed Torx. Now I didn't have such a tool either, but still grabbed some tools and went over there to A) try kludging it, B) gloat about him having purchased this utterly unservicable machine, and C) hold his hand if anything goes wrong.
Now I had thought the easiest would be to just make a fitting flat-head driver and try that, but it didn't work. In the end it was quickest to just make a complete 5-wing Torx.
I didn't take pictures back then, and the original remained with my friend, so I wanted to see if that was just dumb luck, or if the result could be recreated. I got some gadgets from a Flea market today, among which an Ipaq with dead battery, and a bluetooth gps dongle. These have some screws which are slightly smaller than the smallest bits I've got in my toolbox, so I gave it a try. So
(BTW, the camera is from the same flea market, so I'm trying that out at the same time... Excuse the image quality.)

<p>By the time the bit was made your Macbook would be outdated badly.</p>
The hangar wire keeps slipping out of the pliars, then when I get it shaved down small enough (along with scrapes and cuts) to test it out on a screw, the tip simply crumbles and falls apart when I try to use it. Why did someone ever invent torx screws on hard drives? They could have made life a lot easier and used phillips or standard. =.= I'll never find anything that works.
<p>May I humbly suggest an actual torx screwdriver? That will work. You can buy a set of them for just a couple bucks at the right outlets--less than the cost of a hangar, file, a pair of pliers, and the bandages required for the countless nicks and cuts on your hands. I have a six-piece security torx set T5 through T10 for which I paid 2.50. While I truly enjoy seeing how someone was able to fashion a tool from a piece of hangar wire, I would advise people to buy the proper tool when possible.</p>
Frickin hilarious...&quot;If you have plier like hands, Freak.&quot; Right? HAHAHA I come across this all the time...in fact I didn't have a star bit while trying to take off a disc brake on a bicycle yesterday. Had to buy one, but excellent idea,and great job figuring it out.
Well done! I used this patent to make ultra small flat screwdrivers! You did very impressive work!
Good work, any thoughts on trying to heat-treat the bits?<br /> <br /> L<br />
&nbsp;If you are working with mild steel such as a hangar wire, there is not enough carbon in it to really harden. what you can do in that instance is kinda case harden it by supplying carbon. the easiest way to do this is to heat red hot and quench in used motor oil. there is plenty of carbon in there. You might even repeat that step if you want a thicker case. Now If you want to temper it, just rewarm a little and let cool naturally. that's a whole different discussion.&nbsp;
That's the sort of information I was interested in - thanks<br /> <br /> L<br />
Thanks for the kind words, everyone.<br /> wobblestar: That looks pretty good! And huge! My set goes to T45, so I would have been stuck as well...<br /> Using an Allen key to start with is a good idea! But I wouldn't want to waste my files on them, and for the small ones I made here, I don't think I could have used a power tool successfully.<br /> As far as heat-treating goes, I guess it's worth a try. No idea what type of alloy &quot;clothes hanger wire&quot; is, so any suggestions? Just heat it til it glows, then quench it?<br /> Especially the Allen key would benefit from a bit extra hardness.<br />
&nbsp;Hello rimar2000, I did that today! <br /> <br /> I had to remove the steering wheel from a Peugeot 405. There's a big Torx bolt (a T55?) &nbsp;holding the steering wheel on. <br /> <br /> I tried all the local tool shops, but none had the right tool.&nbsp;<br /> <br /> I re-modelled an Allen key using a Dremel. Not pretty, but it worked!<br /> <br /> &nbsp;<br />
Your work is laudable! <br /> <br /> I did this, but on a greater Allen tool, using a &quot;like dremel&quot;.&nbsp;
Never know when this will be handy. Great idea.<br />
