The cross recessed countersunk head screw can also be called a grub screw. The cross recessed countersunk head screw is generally made of metal screw wire pier. After forming, it is in the shape of a cylinder, and the head is flat, such as a slope around the side of the screw. Face, let the screw lock the screw cap or other objects. The top of the Phillips countersunk head screw has a large diameter and can be rounded or hexagonal, allowing tools such as screwdrivers or wrenches to turn the screw. The more prominent top also allows the screw to not drill too far through the material and increase the pressure on the material from the screw.
The thread of the cross recessed countersunk head screw does not need to be matched with the nut during use, and can be directly screwed into the base body for connection and locking. The letter used to describe the tapping screw is "ST". After the Phillips countersunk head screw is screwed in, the Phillips head countersunk head forms a flat surface on the product, which does not affect the appearance and line of the product. The Phillips countersunk head screw is mostly used on non-metallic or thin metal materials with high product appearance requirements. .
