ReidBar™ Half Nut

ReidBar™ Half Nuts are engineered fastening components designed for situations where a full nut cannot be accommodated due to limited space or where precise positioning of ReidBar™ threaded components is required. Manufactured to suit the complete ReidBar™ range, these compact nuts enable secure locking, tensioning, and assembly of anchoring fittings such as the ReidBar™ iPort Flange Anchor, plates, and washer systems.
Their reduced-height profile provides installation flexibility without compromising the mechanical engagement required for structural anchoring applications. As part of the Genuine ReidBar™ system, Half Nuts create a reliable threaded interface in soil and rock anchors, structural bracing, and reinforcing systems where accurate component alignment and clamping are essential.

  • Compact locking nut for confined reinforcement zones Reduced-height profile allows installation where a full nut cannot fit, maintaining structural engagement in limited spaces
  • Ensures accurate positioning of ReidBar™ components Used to set embedment depth and act as a mechanical stop during installation of anchoring systems like the iPort Flange Anchor.
  • Provides secure thread engagement with no re-tapping required Engages directly with the continuous ReidBar™ thread without cutting or machining.
  • Ideal for structural anchoring assemblies Commonly paired with plates, washers, and flange anchors in soil and rock anchors, bracing, and tensioned systems.
  • Integral component of soil and rock anchoring systems Works with domed plates and spherical washers to deliver secure, long-term ground support.
  • Suitable for structural bracing and temporary works Provides reliable fastening for formwork, tie-backs, and restraint systems on site.
  • Maintains performance under ground movement ReidBar's ductility and strain-hardening characteristics support safe anchoring under tensile/shear overload.
  • Rugged thread resists damage Continuous rolled thread withstands handling, installation, and cyclic loading in high-demand applications.
