Anti-burglary screw 4 x 3.5 x 25mm stainless steel
Pay attention! If you need to charge the battery regularly / want to remove the doorbell protector for other reasons, we do not recommend these screws. Parts can no longer be unscrewed by applying anti-burglary screws.
Why choose Anti Burglar Screw
Anti burglary screws are extra secure screws that are often used for secure mounting on the outside of objects.
The one-turn screws are screwed in using a flat head screwdriver. If you need to drive in a lot of these screws, there is of course also a faster way. You can then pre-drill a bit with a 2mm hardwood drill. You can also use an electric screw driver with a special flat head bit. But we do not recommend this because there is too much force on the stainless steel screw, which can cause it to break.
