Through bolt anchor Steel Zinc plated

Article number
Material	Steel
Approval	ETA Option 1
Surface treatment	Zinc plated
Thread	Metric thread
Info	Code = Letter code marking d_o= Nominal diameter of drill bit d_f= Diameter of clearance hole in the fixture h₁= Depth of drilled hole to deepest point h_nom= Minimum hole depth h_ef= Effective anchorage depth t_fix(max) = Grip range s = Width across flats ring ø = Washer diameter S_cr,N = Spacing characteristic C_cr,N = Edge distance characteristic S_min.= Minimal spacing C_min.= Minimal edge distance N_rec= Recommended load in kN T_inst= Tightening torque in Nm The allowable load (N_rec) is valid for one single anchor, at non-cracked concrete (pressure zone) with concrete class C20/25, incl. partial safety factor γ_f= 1,4 and if the S_cr,N and C_cr,N are taken in to account. When reduction on spacing and edge distance take place a re-calculation of forces should be carried out by making use of the technical guide, they are available on request. Final calculations should comply with the complete European Technical Approval (ETA), this approval is also available on request.
