Is there a requirement for the size of the 100 degree flat head machine screws?

The torx groove type is used on the screw fasteners. Then, the six lobe groove type is used on the 100 degree flat head machine screws. Is there any requirement for the six lobe size?

In many cases, the size of the six lobe is related to the diameter of the head of the 100 degree flat head machine screws. The size of the six lobe that can be used for different head diameters is also different.

If you don’t know how to choose the size of the six lobe, you can choose the screw manufacturer that can produce the 100 degree flat head machine screws. They will tell you what type of plum can be used. Or refer to the size of the six lobe marked in the size of the standard countersunk head screw.
