For spacing and distances smaller than the critical ones, strength values have to be reduced depending on the installation parameters.

STATIC VALUES Valid for a single anchor in C20/25 grade concrete when spacing and edge-distance are not limiting parameters.

GENERAL PRINCIPLES:

- Recommended admissible shear and tensile values are compliant with Certificate Nr. 2006/5205/1 released from Politecnico di Milano and obtained by considering a safety factor of 4 for the failure load.

NOTES:

(1) When evaluating the anchor global-strength, the shear strength on the element to be fastened (e.g. timber, concrete, ..) must be considered separately based on the material adopted. (2) All values refer to SKR installed with DIN 9021 (ISO 9073) washer.
