Never fear! Here's a quick and dirty solution.
Step 1: Get a bolt and 2 nuts
* If you're dealing with a car or motorcycle, there's a pretty good chance you'll find one of these suckers holding useless things together, like shocks or fuel pumps.
Now that you have your bolt, make sure it fits. If you've got an oversized one, just file or grind it down to fit.
Step 2: Assemble your tool
If you're planning on using a 12-point socket or box-end wrench, make sure the points will line up with the splines in your wrench.
For 6-point sockets/wrenches, or for those of you using anything open-ended, make sure the nut faces are parallel to each other.
Step 3: Remove your Allen Bolt!
Now, throw that little sucker into your tool kit with pride...you've made your own tool from basically nothing!
