J and J's replacement fasteners are used as direct replacements for old worn, rusted or backing out fasteners. Sometimes called “goof screws”, these fasteners have oversized shank diameters to allow for filling the hole left by a screw that is pulled out. We offer replacement screws in a variety of metals and sizes for all metal roofing applications.
