Metal Panel Screws

The Metal Panel Screws Calculator has functions and data associated with calculating the number of metal panel screws needed for roofs and siding on different shaped structures.

Metal Panel Screws are a specialized product that include a gasket to seal around the screw head and prevent moisture from penetrating the roof or siding through the screw hole, and a screw tip that cuts through the metal panels and is self-starting.  Metal panel screws often come in painted colors to match the metal panels.  The screws are used to attach metal panels to purlins or sheathing for a metal roof or to girts or sheathing for metal siding. Metal Panel Screws are typically used with a density of 75 screws per 100 square feet of metal roofing or siding area.
