Benefits of Hit Anchor

Fast installation
Hit anchors, also known as hammer fixings, can be installed in seconds. A pre-drilled hole is created, the anchor is inserted, and then a hammer is used to drive the fastener and set the expansion mechanism.

 

Versatile applications
These anchors can be used in a wide range of materials, including solid concrete, block, and perforated brick.

 

Removability
Some hit anchors can be unscrewed and removed, offering more flexibility than permanent expansion anchors.

 

Cost-effective
Compared to adhesive anchors, mechanical hit anchors are generally a lower-cost option.

 

Corrosion resistance
Some variants come with corrosion-resistant screws for outdoor use or in moderately corrosive environments.

FAQ

 

Q: What are the main components of a HIT anchor system?

A: The system consists of the chemical adhesive mortar, which comes in a two-part foil pack or cartridge, a mixing nozzle, and the anchoring element, which can be a Hilti HAS threaded rod, HIT-Z anchor rod, or rebar.

Q: How is a HIT anchor installed?

A: The installation process involves drilling a hole to the specified diameter and depth, cleaning the hole of all dust, injecting the mixed adhesive from the bottom of the hole, and then inserting the anchoring element with a twisting motion. The anchor must then be left to cure completely before being loaded.

Q: Can HIT anchors be used in wet or submerged concrete?

A: Yes, some HIT adhesive formulas, such as HIT-HY 200 V3 and HIT-RE 500 V3, are specifically approved for installation in wet concrete and water-filled holes.

Q: What is the difference between a hybrid and an epoxy HIT anchor?

A: Hybrid adhesives (e.g., HIT-HY 200 V3) combine properties of both epoxy and other resins, offering a fast cure time and high performance for heavy-duty anchoring. Epoxy adhesives (e.g., HIT-RE 500 V3) generally have a slower cure but offer the highest ultimate strength and excellent performance for deep embedment and rebar connections.

Q: Are HIT anchors approved for seismic applications?

A: Yes, many Hilti HIT anchors, especially the high-performance epoxies like HIT-RE 500 V3 and some hybrids like HIT-HY 200 V3, have ICC-ES approvals for seismic conditions.

Q: What is the shelf life of a HIT adhesive cartridge?

A: HIT adhesive cartridges have a limited shelf life that is marked on the packaging. To ensure optimal performance, the adhesive should be stored according to manufacturer recommendations (typically in a cool, dry place) and not used past its expiration date.

Q: How does temperature affect HIT anchor performance?

A: Ambient and base material temperature significantly affects the cure time of HIT adhesives. Higher temperatures shorten the cure time, while colder temperatures extend it. Manufacturers provide specific cure time tables that must be followed for safe installation.

Q: Can HIT anchors be used in hollow masonry?

A: Yes, specific HIT systems are designed for hollow base materials like CMU block or hollow brick. These systems often use mesh sleeves (e.g., HIT-SC) to contain the adhesive, which forms a solid plug to secure the anchor.

Q: Can HIT anchors be removed?

A: HIT anchors are designed as permanent fastenings. Once the adhesive cures, the anchor is permanently bonded to the base material and cannot be removed without damaging the concrete or masonry.
