Holztechnic TLL wafer‑head screws are universal structural fasteners for timber projects ranging from small structures to timber buildings. The wide flange head acts as an integrated washer, distributing load to resist pull‑through and wind uplift while accommodating timber movement. A TX30 drive ensures high torque transfer with reduced cam‑out. The partial thread aggressively pulls members together for tight, rigid joints and a neat, low‑profile finish. Made from high‑strength carbon steel with white zinc plating for clean appearance and indoor/covered corrosion protection. Certified for structural applications stressed in any fibre direction and suitable for CLT and dense engineered woods such as LVL.
