304 stainless steel Torx screw anti-theft bolt flat head hexagonal screw countersunk head machine screw M3/M4

The core advantages of 304 stainless steel anti-theft countersunk Torx screws are "anti-theft and anti-disassembly, concealment and flatness, corrosion resistance and rust prevention, as well as fastening stability"

1. The design of the Torx anti-theft slot provides strong anti-tampering and anti-theft capabilities. The screw head features a Torx-shaped inner slot, and some models are equipped with a central column (also known as a Torx column anti-theft slot). Only a dedicated Torx strap wrench can be used for disassembly and assembly, as ordinary straight, cross, and Allen wrenches cannot match it, effectively preventing malicious tampering or theft.
   This feature is suitable for outdoor guardrails, street lamp poles, surveillance camera mounts, community access control systems, safes, display cabinets, and other scenarios requiring tamper resistance, offering far superior security compared to ordinary screws.
2. The countersunk structure is concealed, flat, and non-protruding. The conical design of the countersunk head can be fully embedded into the counterbore of the workpiece, and after tightening, it is flush with the surface of the workpiece, with no protruding parts. It will not scratch passing pedestrians or clothing, nor will it interfere with the operation of equipment components. When exposed, it has a high visual cleanliness, suitable for assembly scenarios that require flat appearance (such as door and window frames, decorative panels, and precision equipment housings).
3. Made of 304 stainless steel, this material is corrosion-resistant and rust-proof in all scenarios, featuring an alloy ratio of 18% chromium and 8% nickel. A dense oxide film forms on its surface, which can withstand the erosion of humid, salt spray (non-coastal high concentration), and mild acid and alkaline environments. It is resistant to rust and corrosion in outdoor, bathroom, and coastal mild salt spray areas after long-term use. There is no risk of plating peeling off, and its service life is 3-5 times that of carbon steel galvanized anti-theft screws. At the same time, the material is non-magnetic, environmentally friendly, and non-toxic, making it suitable for use in scenarios where safety is a priority, such as food machinery and children's play facilities.
