Standard Lengths & Packaging

  • Standard bolt lengths range from 600 to 3000mm in 300mm increments.
  • Non-standard requirements are available by negotiation.
  • Bolts are packaged in bundles.
  • Bolt fittings, such as nuts, anti-friction washers and dome balls, are normally supplied separate with thread bar bolts.




Key Features

  • This bolt is hot rolled with deformations that form a coarse left hand thread (10mm pitch) over its entire length.
  • The thread bar form provides good load transfer properties.
  • The continuous thread provides a high flexibility in
  • The thread bar bolt is normally used with resin anchors, but can be effectively used with cementitious grouts.
  • Corrosion protection may be provided by hot dip galvanizing or alternative coating.
  • Galvanizing may affect performance.
