Holztechnic SNK 5.0mm screws are white zinc‑plated, countersunk fasteners engineered for reliable timber construction. The carbon‑steel core provides excellent tensile and yield strength with very high torsional resistance for secure driving. A deep TX25 recess transfers torque efficiently and resists cam‑out. The partial thread actively pulls members together for tight, rigid joints and a neat, flush finish. Approved for a wide range of structural applications from small construction to timber buildings, and certified for use on CLT and high‑density woods such as LVL. Ideal for interior and covered environments where dependable performance and clean aesthetics are required.
