Ball-End Hex Tools: A Guide
Hex Key, Allen Wrench, L-Key, no matter what name you call it, if you have ever assembled anything you have probably used one. You can get them in Metric or SAE and they come in all kinds of sizes, from the tiny .028 inch to massive one inch. They are commonly used for furniture assembly because they are cheap to manufacture and can be tossed in the box for the customer to use (evidently they are like paperclips at IKEA and they will give you one if you ask nicely).
