SCREW ALIGNMENT
Good alignment of the screws, especially on the wall panels, will give a professional appearance to
the wall panel installation. One way this can be accomplished is by pre-drilling holes in the panels
at identical locations. Up to 15 panels can be stacked together and drilled using a template panel.
Use 1/8” or 5/32” diameter drill bit for panel to structural fasteners and a 1/4” diameter bit for the
sidelap clearance holes. It is important to clean metal shavings off panel surfaces after
drilling to avoid rust stains.
