Hilti HSL-3 sleeved expansion anchor approved for heavy duty applications in cracked concrete

Hilti expansion and undercut anchors

Approved according to the most stringent product qualifications from cracked concrete, fatigue loads as well as ETA seismic C2, heavy-duty anchors are the anchors of choice for demanding and critical fastening applications. 
With our PROFIS Anchor software, the design process becomes quicker, more reliable and specific to your project need. Our specialized engineers can provide additional support by visiting you on site or in your office.

Hilti heavy-duty anchors for steel profiles and baseplates

Steel and metal works

Steel profiles, baseplates and retrofitting elements often require high-performance anchors that can take up both high tensile as well as high shear loads. Heavy-duty anchors are an ideal solution as fewer fastening points are required thanks to the high performance of the anchor.

Piping and equipment

With several fastening points, support of large pipes or groups of pipes are best served by mechanical heavy-duty anchors. Also critical equipment demand the reliability, safety and performance offered by heavy-duty anchors.

Hilti heavy-duty anchors for working platforms and heavy formwork bracings

Temporary fastenings

Working platforms and heavy formwork bracings exert high shear loads and the anchors that are used need to be removable. Hilti HSL and HDA heavy-duty mechanical anchors meet both of these needs as well as ensure easy installation for immediate loading.

    Easy and hassle-free installation

    Installation: Easy and hassle-free

    Suitable for hammer-drilled or diamond-drilled holes, followed by low effort setting. When applying the installation torque, essential for correct functioning of the anchor, the plastic ring ensures effective expansion by preventing rotation of the anchor. The HSL-3-B's torque-controlled setting operation increases installation reliability as it eliminates the need for a torque wrench.

    Convenient inspection

    Post-Installation: Convenient to inspect and easy to remove

    A quality and safety inspection is often required after installation of the anchors. Thanks to their head markings, HSL-3 heavy-duty anchors offer excellent inspection convenience and can be easily removed in case of temporary fastenings, leaving an easily patchable hole. To accommodate the increasing demand of on-site testing, we offer a complete range of testing and evaluation services.
