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
  • do = Nominal diameter of drill bit
  • df = Diameter of clearance hole in the fixture
  • h1 = Depth of drilled hole to deepest point
  • hnom = Minimum hole depth
  • hef = Effective anchorage depth
  • tfix(max) = Grip range
  • s = Width across flats
  • ring ø = Washer diameter
  • Scr,N = Spacing characteristic
  • Ccr,N = Edge distance characteristic
  • Smin. = Minimal spacing
  • Cmin. = Minimal edge distance
  • Nrec = Recommended load in kN
  • Tinst = Tightening torque in Nm
  • The allowable load (Nrec) is valid for one single anchor, at non-cracked concrete (pressure zone) with concrete class C20/25, incl. partial safety factor γf= 1,4 and if the Scr,N and Ccr,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.
