The black PA66 cross-head machine screw (GB/T 818 nylon machine screw) is a non-metallic fastener made by injection molding of polyamide 66 (Nylon 66) engineering plastic. The surface is treated black. The head is a rounded arc-shaped disc with a standard cross slot (PH type), and the thread is metric coarse machine thread (including full thread and half thread). It complies with the GB/T 818 standard. This screw is specifically designed for connection scenarios that require electrical insulation, no magnetism, corrosion resistance, and no damage to the substrate. It is usually used in conjunction with nylon locking nuts or plastic/metal parts with internal threads. The common specifications are M2 to M8.
The product is made by injection molding with PA66 engineering plastic, in accordance with the GB818 standard. The insulation of the product is non-magnetic, which can eliminate electromagnetic interference. It is resistant to acids, alkalis, and oil stains, and will not rust even after long-term use. The self-weight is much lighter than that of metal screws, which can reduce the assembly load. The round design of the head is smooth and does not easily scratch the workpiece. The standard cross-slot is suitable for regular screwdrivers, and the disassembly and assembly are convenient. The applicable temperature range is -30℃ to 100℃. It has elasticity by itself and can play a buffering role. When using, control the tightening force to avoid loosening or breakage.
