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

The M8 Expansion Rawl Bolt is a professional-grade anchoring solution built for high-load applications in solid concrete and masonry. Emphasizing strength and convenience, the M8 metric size and robust sleeve expansion mechanism generate reliable, high-tensile holding power when securely tightened.

This anchor features an external hex head with a large integrated washer/flange, which allows for powerful, high-torque driving using a wrench and distributes the clamping force over a wider surface area of the fixture. Constructed from durable steel and finished with yellow zinc plating (chromate finish), the rawl bolt offers superior protection against rust and corrosion, making it suitable for demanding industrial and mild exterior environments.

Key Benefits

• High Load Capacity: Heavy-duty M8 size and sleeve expansion provide superior tensile and shear strength in solid concrete.

• Torque-Ready Hex Head: External hex design allows for powerful, high-torque driving and easy final tightening with a wrench.

• Load Distribution: Integrated large washer/flange distributes clamping force over a wider fixture surface area.

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

• Reliable Expansion: Robust sleeve ensures secure and fixed anchoring in pre-drilled holes.

Perfect For

• Securing medium to heavy machinery and equipment base plates to concrete floors.

• Mounting structural steel brackets, shelving systems, and railings.

• Installing heavy components in commercial and industrial settings.

• Any application requiring reliable, permanent anchoring into masonry.

Application Instructions

• Drilling: Drill a hole (use the size recommended for M8 anchors) 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 external hex head/nut with a wrench. This action expands the sleeve anchor securely inside the drilled hole.

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

Pro Tips

• Always check the manufacturer’s recommended torque setting for M8 anchors to ensure maximum holding power without cracking the concrete.

• Use a hammer drill and the correct diameter bit for a precise fit.

• Ensure the hole depth is correct; too shallow or too deep will compromise the anchor’s expansion.

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