Special-Shaped Groove Anti-Theft Screw

Special-Shaped Groove Anti-Theft Screw has a self-tapping thread type, which makes it have good self-tapping performance on various materials. The special-shaped groove increases the anti-disassembly ability of the screw, greatly improving the safety performance. Its tensile strength is as high as 450Mpa, the surface hardness is ≥450HV, and the core hardness is between 270-390HV, ensuring the durability and stability of the screw in high-stress environments. The surface is treated with environmentally friendly blue-white zinc, which not only improves the corrosion resistance, but also meets environmental protection requirements, and is suitable for various indoor and outdoor environments. This product can be divided into Y-shaped grooves, square grooves, triangular grooves, and other unconventional structural groove-type anti-theft screws, which are mainly used for railway construction, automobile equipment, power facilities, and road bridges.
