Tackle your interior fitting and timber framing projects with confidence using the Spax 1191010500805 chipboard screws. The t-star plus T20 drive provides maximum bit engagement and prevents cam-out, transferring driving torque directly into your work. Thanks to the countersunk multihead, each steel screw sinks flush into timber and board materials without splitting the wood. With dimensions of 5 x 80 mm and a full thread, these screws deliver high pull-out resistance for rigid, heavy-duty fastening in beams, battens, and panels. Furthermore, the specialized wirox coating shields the steel from corrosion in internal and covered outdoor builds, ensuring long-lasting and clean results every time.
