Fully threaded cylinder head with half-tip
CLT construction
2 SFS / CLT Construction
Application 1: Wood shearingKey advantages:■ Reduced edge distance, minimised blast effect due to the half-tip■ 50% lower fastening torque needed■ No pre-drilling■ Reduced split effect and deep counter sinking is possible because
of head geometry■ Excellent pull out and pressure values ■ Maximum load-bearing capacity

Minimum distances for screw groups upon shear load
In a joint with a screw group subject to stress caused by a force compo-nent in the direction of the shank, the effective number of screws is:
nef = n0,9 n…Number of screws interacting in a joint
Fef = Fv,Rk • nef Fef…effective force
