Intro: How to Unscrew Three Wing (Three-Pronged) Screws Without a Three-Pronged Screwdriver
Hello, first of all
english is not my native language, so I made this post using Google translator.
If you want to take apart device with, three wing or three-pronged screws without a matching screwdriver, try with small torx or hex screwdriver.
For example if you have three wing screw with 5 mm head use TX 5. The point is that screwdriver must cover only center of the screew.
