Shed security screws are often overlooked by shed manufacturers when installing shed doors.
Most UK shed door hinges are strap hinges fixed on the outside of the door. This is great as outward opening doors mean more space inside, but the face fixed hinges are secured using normal pozi-drive screws. This means that any potential burglar can quickly and relatively silently remove three screws per hinge and simply move the door out of the way to gain access to the contents of the shed.

The answer to is use a mixture of screw types or one of a small number of 'tamper proof' screws. I say tamper proof as if you have the right screw bit or are prepared to make a bit of noise then any screw can be undone. But the aim with any part of shed security is to slow down a potential intruder and also to force them to make some noise. This works on the assumption that most shed burglars are opportunists looking for a quick, risk free opportunity to make off with someone else's stuff.
Torx head screws are less commonly used than the Posidrive screw. Also they tend to be mainly used with a powered screwdriver/drill. The standard Torx head has 6 lobes and with vertical sides to the recess is means there is less of a problem with the driver bit jumping out under high load than with a Posidrive head that only has 4 recesses.

To make it less likely that a casual intruder would have the tools to get in a tamper proof torx head has a little metal pin in the centre of the head. This means that a standard torx bit won't work and you need a purpose made bit with a hole in the centre of the head.
This type of screw is driven in to place with a simple slot type screwdriver. Removing the screw is made difficult as the head of the screw is shaped so that it is impossible to simply undo the screw. There are techniques to undo the screw but they are noisy and or time-consuming.

The tamper proof Torx screws suffer from the fact that if the intruder has the right kit they can be removed as simply as the Posidrive screw. This can be an advantage if you need to change the hinges at some point in the future.
However, with the One-way screw, once the screws are in, they are in! There isn't a special driver bit for removing them.
If you absolutely have to remove hinges installed with One-way screws then you will need to grind the heads off with an angle grinder and twist the screws out with a pair of pliers. As I may have said earlier, removing this type of screw is time consuming and noisy for you or a potential intruder.
When installing hinges with one-way screws, the best way to install them is to first of all fit the hinges using posidrive screws. This means that you can make sure that the hinges and door are installed correctly and if you need to make any adjustments then you can easily reposition the hinge and screws.
Once the door is working as you want it, then the screws can be replaced one by one with the one-way screws.
The one-way screws don't need any special bit to install them, a simple straight head screwdriver is all you need.
