The four-corner screw is a specially designed screw whose threaded head has four parallel corner structures, which has a unique appearance and function compared with traditional hexagon screws. This design makes the four-corner screws easier to use when installed and removed, and provides better torque transfer efficiency. The head of the quadrangle screw has four parallel corners, which is different from the common hex screw, making it more prominent in appearance. Due to the design of four corners, the four-angle screws can transmit torque more effectively, making it easier to tighten and loosen it, while reducing the risk of damage. 

 In the production process of quadrangle screws, there are defects such as different height, cross port, hole blockage, multi-paint, deformation, paint loss, etc. Sptek recommends using a cloud disk high-speed visual detector. 

 High-speed visual detector is a special equipment for rapid and efficient visual detection and quality control of products on the production line. Equipped with high-performance cameras, light sources and image processing systems, it can capture images on the product's surface in real time, analyze, identify and identify them in order to detect defects, foreign bodies or other quality problems of the product.
