1, good resilience: low carbon content of SUS410, after heat treatment, avoiding fracture caused by drilling screws excellent.
2, corrosion resistance
3, a well-groomed appearance: self-drilling screw surface is silvery-white, bright as a mirror of the head.
4, high intensity: after the heat treatment, surface hardness of drilling screws can reach more than HV580-HV750, and thus more rapid one stop drilling, self tapping and fastening process. Save time and improve efficiency.
