  • Standard: AS/NZS 1252
  • AS/NZS 4100 specifies conditions for the application of high strength structural bolts in both friction type and bearing type joints
  • Washers can be used under the head of the bolt or the nut
  • Washers help to prevent galling during tightening of the softer structural steel
  • Washers are hardened and tempered to a hardness of HV345 to HV445
  • Rockwell C35-C45 Black & HV270 to HV445 for galvanized
  • Identified by 3 equal spaced projections on the washers periphery
  • High strength structural bolt has a large bolt has a large bolt head and nut because it is designed to withstand full tensioning
  • 8.8/S High strength structural bolts fully tensioned bolts that are used snug tight
  • 8.8/TF High strength structural bolts fully tensioned friction type joint
  • 8.8/TB High strength structural bolts fully tensioned bearing type joint
  • 8.8/TF & 8.8TB bolts as fully tensioned to the requirements of AS/NZS 4100. Cost of tensioning is an important consideration in the use of these bolting categories
