Features & Applications

Features

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

HILTI HST4-R: BEYOND POST-INSTALLED ANCHORS’ STANDARDS

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.
