- do = Nominal diameter of drill bit
- Min. td = Recommended drilling depth
- hef = Effective anchorage depth
- Tinst = Tightening torque in Nm. (screws for class 5.8 or A4-70).
- Allowable load (kN) for a single anchor in pre-stressed hollow-core concrete panels.
- For combinations of tensile loads, shear loads, bending moments as well as reduced edge distances or spacings (anchor groups) see approval.
