Mount DF Screws for PUF Panels
Mount DF Screws for PUF Panels are specialized self drilling fasteners manufactured from Carbon Steel C1022 and developed for insulated sandwich panel installations. Designed in extended length variants (90 mm to 200 mm), these screws allow secure fastening through insulation layers into structural members. Finished with zinc plating for corrosion resistance and requires a magnetic hex socket adapter for installation.
