Grooved cylindrical head screw is a common type of screw, which is usually used to fix parts and provide mechanical connections. It is characterized by a cylindrical head and no slot, which usually requires a screwdriver or torque tool to install or remove it. This screw is suitable for situations that require higher torque and higher appearance requirements, such as furniture manufacturing, mechanical equipment, etc. According to the specific requirements of use, slotted cylindrical head screws can be available in different materials, diameters and lengths. 

 In the production process of grooveless cylindrical head screws, there are external defects such as thread pressure, head groove contamination, head fracture, etc. In response to these appearance problems, Sptek recommends the use of 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 a high-speed camera and processing system, it can quickly capture and process a large number of product images in a short time, and accurately identify and analyze defects, foreign bodies or other quality problems on the product surface. Automatically classify, screen and alarm products.
