Got a small recessed hexagonal screw that’s stuck on a faucet, towel bar, robe hook or on a piece of machinery? If so, grab an Allen wrench, and, if it’s stuck, use this helpful tip.
These little fasteners, called Allen screws, often freeze up over time, due to rust or dirt and when they do, you can easily strip the head long before you can break it free.
How to Loosen Allen Screws
Rather than struggle, strain, and strip the head, insert a punch or nail inside the screw hole instead! Make sure it reaches all the way to the bottom, then tap several times with a hammer and try again.
If it still won’t loosen, add penetrating oil, let it sit overnight, tap again and it should do it!
