WS

In principle, design calculations are performed in accordance with EN 1995-1-1:2004/A1, section 8.

A diameter d of 7 mm is used for this purpose. 19 mm must be deducted from external timber

thickness t1 on one side for the drill point and the remaining timber which is not penetrated.

Design values for WS-T 7mm

In principle, design calculations are performed in accordance with DIN 1052: 2004 08, para. 12.

A diameter d of 7 mm is used for this purpose. 19 mm must be deducted from external timber

thickness t1 on one side for the drill point and the remaining timber which is not penetrated.

* Higher steel strengths can result in failures during insertion in the absence of additionalmeasures and should therefore only be used after consultation with us.

In order to ensure optimum system security we recommend using exclusively WS setting tools. In manualsetting, special attention must be paid to inserting the WS dowel at right-angles.
