How does a four cut screw bolt enhance the fixing effect and installation convenience?

The "four cut" of a four cut screw bolt usually refers to a specific cutting or processing method of the bolt, which makes certain parts of the bolt (usually the threaded part or the end) have four obvious cutting surfaces or cutting edges. This design does not mean that the bolt as a whole has four independent cutting parts, but refers to a special processing method of its thread or end shape, which is designed to provide better fixing effect and installation convenience.

Fixing effect:
Increase friction: The four cut design makes the contact area between the bolt and the substrate more complex, thereby increasing friction and helping to achieve a more secure fixation on hard substrates such as concrete and natural hard stone.
Reduce loosening: Due to the increase in the cutting surface of the thread or the end, the bolt can be more effectively embedded in the substrate when tightened, reducing loosening caused by vibration or long-term load.

Installation convenience:
Quick installation: Four cut screw bolts are usually designed with quick installation features, such as no nuts and washers, which greatly simplifies the installation process and improves work efficiency.
Adapt to a variety of substrates: Since the four-cut design increases the versatility of the bolt, it can achieve a stable fixation on a variety of base materials, including concrete, natural hard stone, concrete hollow brick, solid brick and lightweight aggregate concrete.
Easy to position and adjust: Four cut screw bolts have various head styles, such as hexagonal, flange, countersunk, flat head, etc., which makes it easier to locate and adjust the position of the bolt during installation.
