Silicon Bronze Machine Screw Hex Socket Flat Head
Also known as hexagonal socket screws, they have the characteristics of head screws and pan-head screws in design. Hexagonal inner holes require a hexagonal wrench or hexagonal driver head for loading and unloading. When loading and unloading, you can hold the wrench to adjust the distance and save strength, and can fix the workpiece. Prevent screws from loosening. Compared with traditional external hexagonal screws, internal hexagonal screws are less likely to slip, are not affected by screw rust, and are easy to disassemble.
Products are widely used in automobiles, ships, shipbuilding, electric power industry, electronic parts, mechanical engineering, railways, bridges, aviation and other fields.
