SELF DRILLING SCREW TD HW (ZY) - (KAYU)

Self-drilling screws do not require a pilot hole, which accelerates installation time and lowers the cost and need of additional drill bits.

This extra functionality and cost saving feature makes self-drilling screws the clear choice for metal building construction.

The drill points are numbers #1 through #5 and the amount of steel they can drill through increases as the numbered point increases. 

Typically, self-drilling screws are used in light gauge applications but a #5 drill point can drill through and fasten up 1/2" of steel.

During installation, self-drilling screws will also tap threads to a degree.
