True for single shear connections in solid timber with a characteristic density of 350 kg/m³ (C24) if the fastener is set perpendicular to the grain. Keep the required penetration length in each of the timber members! Thus the fastener must be at least twice as long as the minimum penetration length tmin! All calculations must be verified and signed off by the planner in charge before the work is performed. Lateral Capacity WFD WFO WFR 3/5 Entire fastener range see following pages.
