Hexagonal Cylindrical Head Black Screws

The unique hexagonal design of the internal hexagon cylindrical head bolt enables the use of an internal hexagon wrench for tightening and loosening during installation and disassembly, greatly improving work efficiency. At the same time, the design of the cylindrical head also makes the bolt head smoother, reducing friction with the contact surface and reducing the risk of loosening and slipping.
