Countersunk screw precautions
1. The taper of the reaming should be 90°. To ensure the guarantee, it is better to be less than 90°, not more than 90 °. This is a key trick.
2. If the thickness of the sheet metal is less than the thickness of the head of the countersunk head screw, the screw of the smaller one can be replaced, or the hole can be reamed smaller or not, and the diameter of the bottom hole becomes larger, so that the part pressure is not tight.
3. If there are multiple countersunk screw holes on the part, it should be precise when machining. Once drilled, the assembly is difficult to see, but as long as the error is not large, it can be tightened, because if the diameter of the screw is not very tight when tightening Large (approximately no more than 8mm), when there is an error in the hole pitch, the screw head will be deformed due to the force when it is tightened or loosened.
