With overall partial safety factor for action  = 1,4. The partial safety factors for action depend on the type of loading and shall be taken from national regulations.

The definition of redundant fastening according to Member States is given in the ETAG 001 Part six, Annex 1. In Absence of a definition by a Member States the following default values may be taken.

Minimum number of fixing points 3 4 a)

Minimum number of anchors per fixing point 1 1

Maximum design load of action NSd per fixing pointa) 2 3

The value for maximum design load of actions per fastening point NSd is valid in general that means all fastening points are considered in the design of the redundant structural system. The value NSd may be increased if the failure of one (=most unfavourable) fixing point is taken into account in the design (serviceability and ultimate limit state) of the structural system e.g. suspended ceiling.

Setting instruction *For detailed information on installation see instruction for use given with the package of the product.

Setting instructions Drill hole with drill bit Blow out dust completely Insert anchor with fixture

Hammer down the expansion pin

Check if the pin is completely flattened

Max. exceedance of 2mm can be accepted

In case the pin exceedance is larger than 2mm replace the used drill bit with a new drill bit
