Post Frame Screws
A post frame screw is a long, heavy-gauge fastener with a self-drilling or sharp point and a hex washer head for fixing timber posts, girts and steel cladding. Its coating resists corrosion in exposed agricultural and pole buildings.
It fastens timber framing, purlins, siding and sheet metal on pole barns and post-frame buildings. Agricultural and steel building erectors buy it for quick structural fastening.
