No Recess TRF
For preventing pranks and theft!
You can easily tighten it with a wrench or screwdriver. As you tighten it, the hexagonal head will break off, and the remaining screw will have no recess, making it very difficult to remove with standard tools. Once the screw is installed, it cannot be easily removed, so please handle it with care after confirming the usage conditions.
