Anti-theft screws, also known as tamper-resistant screws, are fasteners designed to prevent the theft of fixed facilities that are permanently installed in outdoor public environments.
They are categorized into two types based on structure and type: installable and removable, and installable but non-removable.
     1. Installable and removable anti-theft screws include: internal pentagon anti-theft screws, internal梅花 (plum blossom) anti-theft screws, internal梅花 with post anti-theft screws, Y-type anti-theft screws, external triangle anti-theft screws, internal triangle anti-theft screws, two-point anti-theft screws, eccentric hole anti-theft screws, and various other structures like internal multi-tooth shapes.
