True for solid timber with a characteristic density of 350 kg/m³ (C24) if the angle between fastener and grain is minimum 45° and maximum 90°. Reduce values between 0° and 45°! Keep the minimum headside penetration length t1 and the minimum pointside penetration length t2 as well as when indicated the minimum member thickness h! Keep the minimum distances to the unloaded edge a4,c (see lateral capacity)! All calculations must be verified and signed off by the planner in charge before the work is performed. 2/5 Entire fastener range see following pages. t1 4,62 Rax,k = 2,74 kN if t2  32 mm  t2 h2 t2 t2 t1 t2 h2 minimum penetration lengths not kept Pull-out of the thread is decisive, see column on the right Pull-out of the thread is decisive, see column on the right   Technical documentation and data sheets 11. 5203/2015 WFD-T-H12-8xL 7049 80544,71 100655,67 847,32 1008,72ı 10065 120848,23 10810,58160 12512,25ı 12084 10010,68 12513,35200 14415,38ı 1008,56ı 605,70120 1009,50ı
