The Masonmate Hex Concrete Screwbolt is designed for professionals and DIY enthusiasts requiring a reliable, heavy-duty anchoring solution for masonry surfaces like concrete, brick, and stone. Its primary benefit is the self-tapping thread design, which eliminates the need for wall plugs or expansion anchors, significantly reducing installation time; however, users should be aware that proper hole diameter is critical for secure anchoring, as over-drilling can compromise the bolt's grip.

No, these are self-tapping bolts designed to cut directly into the masonry. Wall plugs are not required.
You should use a 14mm masonry drill bit, but always check the specific packaging instructions for any recommended deviations based on substrate hardness.
While theoretically removable, it is recommended to use new bolts for critical structural applications to ensure the integrity of the threads.
They are zinc-plated for protection, making them suitable for general outdoor use, but they are not intended for harsh corrosive environments like saltwater coasts.
Performance in hollow bricks is not guaranteed as the threads need a solid material to grip. For hollow materials, a specialist sleeve or resin anchor is usually preferred.
The hole is likely too large. Use a smaller drill bit or a chemical resin anchor to fill the hole before re-attempting.
Ensure the drill bit is not worn down; a slightly worn bit can result in an undersized hole, causing excessive friction.
Check your edge distance. Ensure you are not installing too close to the edge of the concrete slab or brick corner.
For optimal results with the M14 x 130mm bolts, use a high-quality masonry drill bit of the specified diameter to ensure the thread can engage fully with the substrate.
Regarding care, while the zinc plating provides good resistance to typical indoor or sheltered outdoor environments, avoid using these bolts in direct contact with highly caustic materials or exposed marine environments where stainless steel would be required. Store in a dry place to prevent premature oxidation before installation.
