How to install a MALCO self-piercing screw?

To install a MALCO self-piercing screw, use a 1/4 in hex driver bit. Align the screw perpendicular to the sheet metal surface and apply steady pressure while driving at moderate speed. The self-piercing tip cuts its own hole, eliminating pre-drilling. Avoid over-torquing to prevent stripping the zinc-plated steel head.
