5. Installation Instructions

Proper installation is critical for the performance and safety of the Hilti HIS-N insert. Follow these steps carefully:

1. Drill the Hole: Using a rotary hammer drill and a Hilti-approved drill bit of the specified diameter, drill a hole to the required depth in the base material. Ensure the hole is perpendicular to the surface.
2. Clean the Hole: Thoroughly clean the drilled hole using a Hilti brush and blow-out pump to remove all dust and debris. This step is essential for proper bonding.
3. Insert the Capsule (if applicable): If using an adhesive capsule system, insert the capsule into the cleaned hole.
4. Install the Insert: Attach the HIS-N insert to a setting tool (e.g., a rotary hammer with a setting tool attachment). Drive the insert into the hole, rotating it to mix the adhesive (if applicable) and ensure full embedment. Continue until the insert is flush with the surface or at the specified embedment depth.
5. Allow Curing Time: If using an adhesive system, allow the adhesive to cure for the recommended time before applying any load. Refer to the adhesive product's technical data for specific curing times.
6. Attach Fixture: Once the insert is properly set and cured, attach the desired fixture using a compatible threaded rod or bolt. Do not exceed the recommended torque values for the bolt.

Note: Specific drill bit diameters, hole depths, and setting procedures may vary based on the exact application and adhesive system used. Always refer to the detailed technical data sheets provided by Hilti for your specific project.

6. Operating Instructions

Once the Hilti HIS-N insert is correctly installed and cured, it functions as a reliable anchor point. To operate, simply thread a compatible bolt or threaded rod into the internal threads of the insert. Ensure the bolt engages sufficient threads for a secure connection. Do not overtighten the bolt, as this can damage the internal threads of the insert or the attached fixture.

7. Maintenance

Hilti HIS-N Carbon Steel Internally Threaded Inserts are designed for long-term, maintenance-free performance once properly installed. However, periodic inspection of the attached fixture and the surrounding base material is recommended, especially in dynamic or critical applications. Check for:

• Signs of corrosion on the exposed portion of the insert or attached bolt.
• Cracks or damage to the base material around the insert.
• Loosening of the attached bolt.

If any issues are observed, consult a qualified professional for assessment and corrective action.

8. Troubleshooting

While Hilti HIS-N inserts are robust, issues can arise from improper installation or application. Here are some common concerns:

• Insert spins during installation: This often indicates an oversized drilled hole or insufficient cleaning. Ensure the correct drill bit is used and the hole is thoroughly cleaned.
• Bolt does not thread smoothly: Check for debris in the internal threads or cross-threading. Clean the threads and ensure the bolt is aligned correctly. Do not force the bolt.
• Fixture feels loose after installation: This could be due to improper embedment depth, insufficient curing time of adhesive, or damage to the base material. Re-evaluate the installation process and base material integrity.

For persistent issues or complex problems, contact Hilti technical support.
