is an essential component in a variety of construction and carpentry projects. These screws feature a flat-head design that lies flush with the surface of the material being fastened, providing a smooth, refined appearance. The term "galvanized" refers to the protective zinc coating applied to screws to help prevent corrosion and rust, making them ideal for both indoor and outdoor applications.

1. The expansion taper of the should be 90 degree . It is very critical to ensure that it is better to be <90° than >90 degree .
2. If the thickness of the sheet metal is smaller than the thickness of the head of the countersunk screw, you can change the screw to a smaller size, or you would rather enlarge the hole smaller than enlarging the bottom hole so that the diameter of the bottom hole becomes larger and the parts cannot be pressed tightly.
3. If there are multiple countersunk screw holes on the part, be more precise when processing. Once drilled crookedly, the assembly will be ugly. However, as long as the error is not large, it can be tightened, because when tightening, if the diameter of the screw is Less than or equal to 8mm , when there is an error in the hole spacing, the round head of the cross countersunk head screw will be deformed due to stress when tightened.
