Key Features

  • Manufactured from a special hot rolled deformed bar designed by DSI.
  • This bolt features a rib pattern which actively assists with mixing the chemical anchors during installation.
  • The deformed bar rib pattern improves load transfer properties.
  • The rolled thread strength nominally equals the column strength of the bar.
  • The 24mm chemical anchor bolt is designed to be used with chemical anchors, but can be effectively used with cementitious grouts.
  • Corrosion protection may be provided by hot dip galvanizing or alternative coatings.
  • Australian Patent Number 536627 is applicable to the bar design of this bolt.

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 with threads protected by heavy duty polyethylene bags.
Bolt fittings, such as nuts, anti-friction washers and domed balls, are supplied fitted to rock bolts in the configuration requested.
     Installation Guide Lines

    • 27-28mm hole diameters are preferred. If larger diameter holes are to be used refer to "Posimix" bolt on data sheet WS.
    • Hole depth is critical. Hole depth should be shorter than the bolt to allow for the height of the washer and nut.
    • It is important to follow the resin anchor recommended mixing and hold times as printed on the chemical anchor cartons.
    • DO NOT OVER MIX.
