A screw is a tool that uses the physics and mathematics principles of the oblique circular rotation of the object and the friction force to gradually tighten the objects and parts. So do you know what its types are? Follow the editor of Big Round Head Screw to have a simple understanding!
1. Slotted ordinary screws
It is mostly used for the connection of smaller parts. It has pan head screws, cylindrical head screws, half countersunk head screws and countersunk head screws. The head strength of pan-head screws and cylinder-head screws is relatively high, and they are connected to common parts; the head of the half countersunk head screw is arc-shaped, and its top is slightly exposed after installation, and it is beautiful and smooth. It is generally used for instruments or On precision machinery; countersunk screws are used where the nail heads are not allowed to be exposed.


2. Hexagon socket and hexagon socket screw
The head of this type of screw can be embedded in the component, can apply a larger torque, and the connection strength is higher, and it can replace the hexagonal bolt. It is often used in joints with compact structure and smooth appearance.
3. Cross recessed ordinary screws
It has similar functions to ordinary slotted screws and can be replaced with each other, but the cross-slotted ordinary screws have higher groove strength, are not easy to be bald, and have a more beautiful appearance. When in use, the cross-shaped screwdriver must be used for loading and unloading.
4. Eyebolts
The eyebolt is a kind of hardware accessory for load-bearing during installation and transportation. When in use, the screw must be screwed to the position where the supporting surface fits tightly. No tools are allowed to be tightened, and no load perpendicular to the plane of the lifting ring is allowed to act on it.
