Concrete screw anchors

Reliable design and installation for all fastening in concrete applications

Whether you're designing baseplates or installing temporary anchors for formwork, concrete screw anchors are more efficient and productive than other solutions, without compromising quality and safety.

For both permanent or temporary fixings, HUS4 concrete screws offer easy setting and high structural safety, even in the toughest site conditions. And by adding a HUS4 MAX capsule to the borehole, you'll unlock the performance benefits of a chemical anchor in the time it takes to drive a screw.

Why choose concrete screw anchors?

Faster, easier installation

No cleaning, no torquing, no hammering, no waiting for curing and no special accessories required. Just drill, drive and load.

Safer solutions

Achieve high structural safety in cracked concrete, fresh concrete, hollow-core slabs or masonry, even with tight spacing.

Design flexibility

Anticipate future design needs by adding a mortar capsule to increase performance by up to 30% while enabling full removability.

More productive installation

HUS4 screws deliver ultimate performance with faster, easier setting

Whether you're installing permanent or temporary fastenings, HUS4 concrete screws support loads similar to wedge anchors but set up to 2x faster thanks to a smaller drilling diameter with no cleaning or torquing and less blocking.

For the performance of a chemical anchor but without the installation hassles, insert a HUS4 MAX mortar capsule into the hole before driving the HUS4 screw and you're ready to load – no waiting for the chemical to cure with instant curing and without needing mortar dispenser or any other special accessories.

MEP fastening

  • Ideal for overhead work: no more finagling awkward drop-in anchors
  • More applications: expanded portfolio features sizes 8mm-16mm and hexagonal, threaded and countersunk heads
  • Quick fastening of channels and brackets thanks to a shallow hole that doesn't need cleaning
  • No special tools required – just a hammer drill or rotary hammer and an impact wrench

Temporary fastening

  • Ideal for working platforms, tilt-ups, safety railing, perimeter barriers and prefab connections
  • DIBt-approved Hilti check gauge for reusability in fresh concrete, helping save money with a high level of safety
  • More reuses than other screw anchors thanks to a new design
  • Works for large formworks fastened to fresh concrete and hollow-core slabs

Industrial equipment fastening

  • Ultimate-performance fastening reduces the chance of business interruptions due to anchor failure
  • No waiting for curing – load immediately for maximum jobsite productivity
  • Removable, adjustable and reuseable in the same borehole, allowing for more flexibility with functional changes
  • Borehole water-tight sealing ensuring protection against humidity

More design flexibility

Mechanical or chemical anchor? Enjoy the benefits of both with HUS4 Hybrid

HUS4 Hybrid is our new versatile baseplate anchoring system. Comprising of a HUS4 screw and a HUS4 MAX mortar capsule, it combines the advantages of both mechanical and chemical anchors, giving you peace of mind that you chose the right anchor regardless of conditions.

Poor concrete quality? The mortar will help improve structural safety. Non-ideal temperatures? The screw won't be affected. Last-minute changes? Remove, adjust and even reuse the same hole! No borehole cleaning and leave your chemical dispensers at home.

Structural baseplate applications

  • High structural safety with double holding function in columns, beams, rafters, trusses, lattice girders and its secondary members as well as seismic loads (C1), regardless of jobsite conditions
  • Tension performance close to chemical anchors 
  • Extended portfolio up to 16mm, plus new threaded head configuration
  • Adjustable and removable even after curing; approved for reuse of the same fastening point

Safety relevant applications

  • Ideal for non-structural but safety-relevant applications such as handrails, roofs and lightweight steel structures
  • Smaller edge and spacing requirements than wedge anchors
  • Threaded heads available for standoff design
  • Water-tight borehole sealing
