M8 Eye Expansion Rawl Bolt – Secure, High-Tensile Anchor for Concrete and Masonry

The M8 Eye Expansion Rawl Bolt is a professional-grade anchoring solution built for high-load applications in solid masonry and concrete. This M8 (8mm) metric anchor utilizes a robust sleeve expansion mechanism: as the external nut is tightened, the anchor sleeve expands, generating exceptional, high-tensile holding power within the drilled hole.

The anchor features a closed eye end, which provides a secure, permanent attachment point for rigging, safety chains, cables, or heavy overhead loads. Constructed from durable steel and finished with yellow zinc plating (chromate finish), the rawl bolt offers enhanced protection against rust and corrosion, making it suitable for interior and mild exterior environments.

Key Benefits

• High Load Capacity: Heavy-duty sleeve design provides strong, reliable holding power in concrete and brick.

• Permanent Anchor Point: Features a closed eye for securely attaching cables, chains, or overhead supports.

• Corrosion Resistance: Yellow zinc plating (yellow chromate) offers enhanced protection against rust, suitable for mild exterior use.

• M8 Standard: Standard 8mm metric thread size is compatible with common hex tools and load calculations.

• Pre-Assembled: Comes complete with the nut, washer, and sleeve, ready for immediate installation.

Technical Specifications

• Product Type: Eye Expansion Rawl Bolt / Sleeve Anchor

• Size: M8 (8mm Metric Thread Diameter)

Perfect For

• Installing heavy shelving, railings, or equipment into concrete walls.

• Securing large guy wires, safety cables, or barrier chains to the floor or ceiling.

• Overhead rigging for lighting, pipes, or vents in commercial buildings.

• Any application requiring a robust, permanent anchor point with an open loop.

Application Instructions

• Drilling: Drill a hole (use the size recommended for M8 anchors, typically 12-14mm) into the masonry/concrete to the specified depth using a hammer drill.

• Cleaning: Clean the hole thoroughly of all dust and debris.

• Insertion: Insert the anchor bolt completely into the hole.

• Tightening: Turn the hex nut with a wrench. This action draws the eye bolt outwards, expanding the sleeve anchor securely inside the drilled hole.

• Checking: Ensure the anchor is tight and secure before applying load.

Pro Tips

• Always check the drill bit size against the anchor specifications for a perfect, secure fit.

• Ensure the hole depth is correct; too shallow or too deep will compromise the holding power.

• Clean the drilled hole thoroughly with a brush and vacuum to maximize the friction and grip of the expansion sleeve.

• Do not reuse the anchor once it has been fully tightened and removed.
