Features & Applications

  • Innovative performance – our next-generation anchors offer improved concrete capacity and pull-out loads, allowing you to optimise baseplate size and anchor usage and get more value out of your materials
  • Unlock flexibility – anchors can be securely installed in shallow embedment depths for productivity and deep embedment depths for increased performance with flexible edge and spacing distances
  • Faster and easier installation – install our full range of anchors quickly with our Adaptive Torque compatible tools and without the need for borehole cleaning
  • Safer and more reliable – patented anti-spin expansion cone designed to eliminate spinning issues for a more reliable anchor installation
  • Cost-saving design – pair with PROFIS Engineering software to simplify the design of steel-concrete connections and reduce material costs
  • Fastening baseplates, handrails, façade systems, and mechanical, electrical or plumbing supports to concrete
  • Fastening in cracked and uncracked concrete required for building code compliance
  • Qualified to resist seismic actions and loads; for full coverage of ETA approved C1 and C2 critical connection requirements
  • Suitable for dry indoor and outdoor use
  • Qualified to resist seismic actions and loads; for full coverage of ACI compatible design requirements

Our highest performing wedge expansion anchor for bearing high static and seismic loads

HST4-R is our latest innovation, bringing stud technology beyond the existing post-installed anchors' approval standards while meeting the evolving needs of both designers and contractors. These anchors are engineered to withstand high loads and harsh environmental conditions.


Stud anchors are widely used for fast and reliable fastening to concrete, and are especially suitable for baseplate fixing, façade brackets, and curtain walls, as well as service fixings in civil infrastructure (e.g. tunnels, bridges, noise barriers) and industrial fastenings (e.g. machine and conveyor belt fixings). However, stud anchors have shown limitations in terms of performance and design flexibility when compared to cast-in or chemical anchors.
