2. Safety Information
Always prioritize safety during installation. Failure to follow safety guidelines can result in injury or property damage.
- Wear appropriate personal protective equipment (PPE), including safety glasses, gloves, and hearing protection.
- Ensure the work area is clear of obstructions and well-lit.
- Use tools in good working condition and as intended by the manufacturer.
- Verify the integrity of the base material (concrete/masonry) before drilling and installation.
- Do not overtighten the anchor, as this can damage the base material or the anchor itself.
- Consult local building codes and regulations for specific requirements.
3. Setup and Required Tools
3.1 Tools Required
- Rotary hammer drill
- Carbide drill bit (1/2 inch diameter, specifically for concrete/masonry)
- Wire brush or compressed air for hole cleaning
- Torque wrench or impact wrench with appropriate hex socket (e.g., 3/4 inch or 19mm for 1/2" anchor)
- Measuring tape and marking tool
- Personal Protective Equipment (PPE)
3.2 Preparation
- Mark the Location: Clearly mark the precise location for each anchor on the concrete or masonry surface.
- Select Drill Bit: Use a 1/2 inch diameter carbide-tipped drill bit suitable for concrete or masonry.
- Set Drill Depth: Adjust the drill stop on your rotary hammer drill to ensure the correct hole depth. The hole depth should be at least 1/2 inch deeper than the anchor's embedment depth to allow for dust accumulation. For a 5-inch anchor, the hole should be approximately 5.5 inches deep.
4. Operating (Installation) Instructions
Follow these steps carefully for optimal performance and secure fastening.
- Drill the Hole: Using a rotary hammer drill and the specified 1/2 inch carbide drill bit, drill a hole perpendicular to the surface at the marked location. Ensure the hole is drilled to the correct depth (anchor length + 1/2 inch).
- Clean the Hole: Thoroughly clean the drilled hole using a wire brush and compressed air. Remove all dust and debris to ensure proper engagement of the anchor threads. A clean hole is critical for achieving specified holding values.
- Insert the Anchor: Place the Titen HD screw anchor into the cleaned hole.
- Drive the Anchor: Using an impact wrench or torque wrench with the appropriate hex socket, drive the anchor into the hole until the washer head is flush with the surface of the fixture or base material.
- For optimal performance, ensure the anchor is driven straight.
- Avoid over-torquing, which can strip the threads in the concrete or damage the anchor.
- Note: In very old or hard concrete, the anchor may be difficult to drive to full depth. If resistance is excessive, consider using a different anchoring solution or consulting a professional. Do not force the anchor, as this can lead to shearing.
- Verify Installation: Once installed, the anchor should be firmly seated and provide a secure connection.
5. Maintenance
Titen HD screw anchors are designed for long-term, maintenance-free performance once properly installed. However, periodic inspection of the fastened assembly is recommended, especially in critical applications or environments subject to vibration or extreme conditions.
- Inspect anchors for any signs of corrosion, loosening, or damage.
- If an anchor appears damaged or loose, it should be replaced. Do not reuse anchors that have been removed.
- Ensure the surrounding concrete or masonry remains in good condition. Cracks or deterioration in the base material can compromise anchor performance.
