If you want to remove this kind of bolt, you must use the matching professional tool to remove it. Using this kind of fastener can well protect the privacy of the owner.

Even if it is disassembled, there will be disassembly marks without supporting tools, so that the owner can know that someone has moved his things.

The patented design is configured to keep out Torx-Pin, Hex-Pin, and all other tamper-resistant bits.
