Product Material

The main material of these screws is usually carbon steel, which is cost-effective and has sufficient hardness for daily fastening needs. Some models use alloy steel for occasions that require higher strength. The turning process ensures the screw thread is smooth, allowing it to twist into workpieces easily without jamming. The black surface is formed by oxidation treatment, which enhances rust resistance compared to untreated screws. This treatment also makes the surface uniform in color, without extra decorations. The material selection is based on practical use requirements, not excessive performance pursuit. The screws can bear normal loads in general environments, and the material won’t break or deform easily during installation and use, meeting basic fastening demands of most scenarios.
