Hilti capsules and chemical anchors are two crucial supplies that offer durability and dependability when it comes to fastening structures to concrete. For heavy-duty applications where conventional mechanical fasteners might not be sufficient, these solutions are especially helpful. For any construction project to be safe and long-lasting, it is essential to know how to calculate and use these anchors correctly.
Chemical anchors attach a metal rod or bolt to the concrete using an adhesive or resin. This technique provides a robust, long-lasting bond and works particularly well in difficult situations where the concrete is weaker or cracked. The resin is a great option for high-load applications because it fills in any gaps and solidifies to form a bond.
Conversely, Hilti capsules are a particular kind of chemical anchor that makes the procedure even more straightforward. When you place these capsules into a drilled hole, the pre-filled resin and hardener inside will mix. Professionals favor this pre-packaged approach because it saves time and lowers the possibility of mixing errors.
It is imperative to adhere to appropriate load-bearing capacity and installation techniques in order to achieve optimal results. By doing this, you can be sure that the anchors you use will hold up well to the anticipated loads. Comprehending these tools can have a big impact on the result of your work, regardless of how big or small the project you’re working on is.
Knowing how to calculate and use Hilti capsules and chemical anchors is essential to guaranteeing solid and dependable connections in concrete. These tools offer a reliable way to fasten fixtures and reinforcements, but how well they work depends on how precisely they are calculated and applied. The use of Hilti capsules and chemical anchors will be explained in detail in this article, along with how to choose the best type for your project and install them for maximum strength and durability.

Hilti chemical capsule anchors
This type of chemical anchor is clearly dosed for the installation of only one fastener. It is a polyethylene container of cylindrical shape filled with adhesive composition. Two components of the adhesive mixture are separated by an impermeable partition. Mixing of the components of the mixture occurs during installation. Products of this type are marked with the letters HVU, indicating the thread of the anchor stud and the depth of the mounting hole for it. For example, the marking “HVU M16X125” means that this capsule is designed for fastening an anchor stud with an M16 thread, a hole depth in concrete of 125 mm. The range of capsules is presented quite widely: from M8 to M39.
Using an adhesive capsule to install a stud is a fairly straightforward technological process:
- Drill a hole of the required diameter and depth in the base. The manufacturer recommends choosing a drill or auger diameter for studs M8÷M16 2 mm larger, for M20÷M39 3÷4 mm larger. For example, for the “HVU M12X110” capsule you will need a drill with a diameter of 14 mm, hole depth 110 mm.
- We thoroughly clean the hole from dust using air or a brush.
- We insert the capsule into the hole.
- We screw the stud into the hole clockwise: the lower end of the stud breaks the capsule and when screwed in, the components of the adhesive composition are mixed.
The adhesive composition’s final hardening time, which determines when the stud can withstand its maximum loads, varies depending on the outside temperature. It can take anywhere from 20 minutes at +20˚Ρ to 5 hours at -5˚Ρ.
The company has created special capsules called "HVU-TZ" for studs that are under increased dynamic loads. These kinds of capsules are made to fit stud sizes ranging from M10 to M20.
Hilti injection anchor systems
This kind of chemical anchor is a plastic cartridge with two sealed foil containers (one containing adhesive filler and the other containing hardener); it is identified by the letters HIT. The company currently offers seven different varieties of this kind of chemical anchor. The cartridge capacity (which comes in two varieties: 330 and 500 ml), compositional ingredients, application area, and load—which can sustain the hairpin established with its use—all affect how much these anchors cost.
One chemical anchor of the budget class is the universal hybrid composition "HIT-MM-Plus," which costs 650 ÷ 900 rubles for a single cartridge with a 330 ml capacity. The foundation of two-component glue is uretan-metacrylate. Installing studs with a thread size in the M6 ÷ M16 range is advised for primary building materials like concrete, hollow and whole brick, lime-sand blocks, artificial and natural stone, and concrete cells. The company provides specially designed perforated plastic sleeves that increase the strength of the fastening and decrease the amount of adhesive needed to fasten studs in hollow blocks and bricks.
Additionally, the composition "HIT-RE-500-V3," which closes the injection anchor line, costs 2700 ÷ 3300 rubles for a package containing 330 ml and is meant to be used for gluing the releases of the load-bearing reinforcement of stair flights, floors, columns, and foundations. Composition based on epoxy glue with additives that let you install reinforcement bars and studs with a 10 × 55 mm diameter even in holes that are totally submerged in water.
The glue’s constituent parts are extracted with the aid of a mechanical manual dispenser. The "HDM-330" dispenser is designed for chemical anchors with a 330 ml capacity, while the "HDM-500" dispenser is meant for 500 ml. The capsules are placed into the dispenser’s plastic cassette, which comes with the kit. The mixer is then screwed onto the cartridge’s threaded section, which holds the cartridge containing the adhesive composition’s components, and the glue is injected into the drilled hole through the tube’s conical shape. The dispenser handle is fitted with parallel pistons that, when pressed once, dispense approximately 5 milliliters of the adhesive composition.
Using the "HIT-MM-Plus" composition and the "HDM-330" dispenser is demonstrated in this video:
When producing large quantities of anchoring work, professionals should utilize the battery dispenser (HDE-500-A22) and pneumatic dispenser (P-8000-D).

| Chemical Anchors | These are special adhesives used to secure bolts or other fixtures into concrete. They come in various types, such as epoxy or polyester, and are designed to provide a strong hold. They"re especially useful when the concrete is old or not ideal for mechanical anchors. |
| Hilti Capsules | Hilti capsules are a type of chemical anchor system that includes a pre-filled capsule with the adhesive. When inserted into a drill hole, the capsule breaks, mixing the adhesive inside. This system simplifies the application process and ensures a consistent mix. |
| Calculation of Chemical Anchors | To determine the right amount and type of chemical anchor needed, factors like load requirements, concrete strength, and anchor placement are considered. Proper calculations ensure that the anchors can handle the intended load safely. |
| Application of Chemical Anchors | Applying chemical anchors involves drilling a hole, cleaning it, inserting the anchor or capsule, and allowing the adhesive to cure. The curing time depends on the adhesive used and environmental conditions. |
Knowing how to calculate and apply Hilti capsules and chemical anchors is crucial when it comes to securing fixtures and equipment. These techniques, each with special advantages, provide dependable solutions for anchoring in concrete. Even in less-than-ideal circumstances, chemical anchors allow you to create strong, long-lasting connections. Hilti capsules, on the other hand, offer an easy-to-handle and apply anchoring solution that is quick and effective.
To make sure that your anchors function as intended, accurate computation is essential. This entails taking into account elements such as anchor placement, concrete quality, and load requirements. Precise computations avert overloading and guarantee the durability of the anchors over time. When used properly, these anchors provide a strong base for a number of uses, including mounting large machinery and providing structural support.
In conclusion, Hilti capsules and chemical anchors are both useful equipment for working with concrete. Installs will be more secure and long-lasting if you know how to calculate and apply their requirements. Whether you’re working on a large construction project or a small do-it-yourself project, knowing these techniques will guarantee that your work will last.
