The Forgefix Masonry Anchor Projection Bolt is designed for professional contractors and serious DIY enthusiasts requiring a heavy-duty, reliable fastening solution for masonry substrates. Its primary benefit is the combination of a four-way expansion shield and a projection design that allows for easy fixture removal without the need to replace the anchor, though users should note that these require a precise drill diameter to ensure the expansion mechanism functions correctly.

No, these expansion anchors require solid masonry or concrete to create the necessary friction for the expansion shield to hold.
This finish provides a sacrificial protective layer that significantly delays the onset of corrosion and rust compared to standard untreated steel.
Yes, the projection bolt design allows you to unscrew the nut and remove the fixture, leaving the expansion shield embedded in the masonry.
You should always drill slightly deeper than the anchor length to account for the shield expansion and to provide a space for any incidental dust collection.
No, you only need a standard masonry drill bit of the correct size and a suitable spanner to tighten the nut.
The drill hole is likely too large; ensure you are using a drill bit that matches the manufacturer's specified diameter for the anchor size.
Clear all dust and debris from the hole using a drill brush or compressed air, and ensure the hole is drilled to the correct depth.
Check that the bolt threads are not damaged or clogged with masonry dust. If resistance is high, back the nut off, clean the threads, and try again.
Installation requires a rotary hammer drill and a masonry bit matching the diameter of the anchor sleeve. Always drill to a depth slightly deeper than the length of the anchor to allow for space beneath the sleeve. Insert the anchor into the hole and tighten the nut with a spanner; as the nut is tightened, the cone is pulled into the shield, forcing it outward to grip the masonry. While the Zinc Yellow Passivated finish provides strong rust protection, avoid using these in highly acidic or marine environments where stainless steel may be required. Regularly inspect tightened nuts for signs of loosening caused by vibration, especially when securing dynamic loads like guy ropes.
