Holztechnic TLL screws are universal flange‑head fasteners for structural timber—from small structures to large timber buildings. The wide wafer head acts as an integrated washer, spreading load to resist pull‑through and uplift, ideal where wind actions or timber movement occur. A TX40 recess provides secure torque transfer and reduced cam‑out, while the partial thread actively draws members together for rigid, squeak‑free joints. Manufactured 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.
