M12 Expansion Rawl Bolt

M12 Heavy Duty Expansion Rawl Bolt – Maximum Load Capacity Anchor for Concrete and Masonry

The M12 Heavy Duty Expansion Rawl Bolt is a professional-grade, structural anchoring solution engineered for maximum load bearing in concrete and solid masonry. Emphasizing strength, the M12 metric size and robust sleeve expansion mechanism generate reliable, high-tensile holding power when securely tightened.

This anchor features a large mushroom/flanged head with an integral washer, which is designed to distribute the clamping force over a wider surface area of the fixture, enhancing stability and preventing fixture damage. 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

Maximum Load Capacity: Heavy-duty M12 size and sleeve design provide superior tensile and shear strength in solid concrete.
Load Distribution: Large flanged head distributes clamping force over a wider fixture surface area for enhanced stability.
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.
Pre-Assembled: Comes complete with all necessary expansion components, ready for immediate installation.

Application Instructions

Drilling: Drill a hole (use the size recommended for M12 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 nut with a wrench. This action pulls the bolt, 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 anchor’s length and embedment depth are adequate for the required load.
Do not reuse the anchor once it has been fully tightened and removed.
Clean the drilled hole thoroughly with a brush and vacuum to maximize the friction and grip of the expansion sleeve.
