Hilti’s Versatile & High Performance Anchors

HST Anchor

With HST (stud anchor from Hilti), fastenings can be made where safety is at stake, even in worse type of climatic conditions. It can be used for fixing all types of insert plates, cantilever structure, and PEBs fixing and high load applications.

It has European Technical Approval (ETA) for use in cracked and un-cracked concrete. Therefore, HST is an anchor suitable for all kinds of concrete. Very versatile and easy to use and install because of the features it offers. HST has been used to fasten large air expellers in the tunnels and industries due to its special approvals and cold forming.

HST comes in several versions such as carbon steel, stainless steel and High corrosion resistant material. All the versions are made available to ensure the product suitability for coastal and non-coastal areas and highly corrosive environment.

It is a cold formed anchor thus anchors when bent during torqueing inside the concrete doesn’t break and holds the loads applied on it. It has been supplied to fasten external and internal ladders/ steel or iron structures on chimneys/ poles across various trades and applications.

HST is approved for use in tension zone, tested for shock loading and fire. Thus it is easily used for structured fixings and offers peace of mind. It is also used to fix the railings and crash barrier where the sudden shock loads are very common. This is possible owing to the shock load approval and cold forming process with HST. It can also be used for emergency fixings such as steel steps at emergency exits in commercial / residential buildings. Chair fixings in the stadiums and conference rooms are also promoted with HST by several OEMs across India.

Thus HST is an answer to many of the applications that are encountered on a day- to-day basis on jobsites.

HRD Anchor

HRD is another anchor with versatile portfolio of applications. It is used to fasten everything everywhere; it can be used to fix structures in concrete and brick. It can also be used in cracked and uncracked concrete and is approved in solid and hollow masonry and in autoclaved aerated concrete.

Door and window frame of any material can be fixed easily with HRD and with approved loading charts for two different embedment depths. Because of unbeatable features, this anchor fastener is popular and can be seen easily on almost all the jobsites across India.



Another popular application is Jamb fixing wherein a stone is fixed with the HRD in brick or concrete to hold the stone in vertical and overhead conditions.

Other areas of applications include stone façade for fixing a facade clamp to the base material so as to hold the stone in place. It is actively used for fixing the railing when the base material is brick (hollow / solid).

HSL Anchor

HSL is an anchor that is proven for its load taking abilities both for shear and tensile forces. HSL is capable of taking fatigue load, seismic load and high shear loads. It has approvals for fire, nuclear power plants, shock load, seismic load, cracked concrete usage, and fatigue loads.

It is available in carbon steel, stainless steel and 8.8 grade of steel. This anchor can suffice all the heavy duty fastenings with ease. It comes with various heads so as to suit the need of the application.

A unique feature of this anchor is a red cap indicator that guarantees the correct installation torque and thus avoids over tightening hence prevents damage to anchor and base material.

HSL is capable of fastening a bent insert plate correctly to the base material.

HSL has been used in projects to fix individual MS Plate of 100X100X6 to hold the wire mesh & geotextile membrane assembly in contiguous pile. It also helps in fixing of heavy duty industrial equipment base plates. This is an anchor that is perfectly designed for fixing heavy trusses, overhead crane fixings in industrial applications, Pre-engineered buildings and overhead steel walkways, ISMB in commercial buildings and any cantilever structure with high shear loads.

HSL is also suitable for the canopy fixings, multilevel parking and emergency exit ladders and railings of a commercial and residential building. In addition, this anchor is used extensively in cement plants and power plants owing to higher safety standards. It is actively used in the retrofitting and rehabilitation projects across India. For strengthening of column and beams, no other anchor stands near to the HSL position. It is the first choice of the consultants for rehabilitation projects.

To summarize, HSL is high performance anchor which improves reliability of structure, provides enhanced safety, and increases productivity.
