Feature:1. High quality stainless steel material, with high hardness, wear resistance and durability, used as a drive shaft accessory for intelligent robots, and also suitable for lathe equipment and engineering equipment.2. The 5mm stainless steel hexagonal shaft has an outer diameter of 5mm and an appearance of a hex with a plane spacing of 4 mm. It is a perfect combination of a circular shaft with a diameter of 5mm and a hex with a plane spacing of 4 mm. It has the advantages of round shaft and hexagonal shaft.3. You can use a metal cutting blade to cut the 5mm stainless steel hexagonal shaft to your own customized length according to your needs.4. Can be used with other robot parts and accessories with matching hexagonal holes, which can effectively prevent the parts from rotating and slipping on the hexagonal shaft, so that the force of the parts is more even, and the friction and the efficiency of transmission or driving force are greatly increased.5. Can also pass through a bearing with an inner diameter of 5mm and use it with other robot parts with matching hexagonal holes, which greatly enhances the load bearing and transmission capacity of the robot parts.Specification:Item Type: Hex ShaftMaterial: Stainless SteelModel: 4102-0005-0400Uses: Used As a Drive Shaft Accessory for Intelligent Robots, and Also Suitable for Lathe Equipment and Engineering Equipment.Package List:4 x Hex ShaftNote:1. Match the design size when using.2. When cutting the design size by yourself, operate under professional guidance to ensure safety
