Product Information
Full details
The Masonmate Hex Concrete Screwbolt is designed for construction professionals and DIY enthusiasts who need a reliable, high-strength anchor for fastening into concrete, brick, block, and stone. Its primary benefit is the self-tapping thread design, which eliminates the need for wall plugs, significantly reducing installation time. However, users should note that the zinc-plated finish is best suited for interior or sheltered exterior environments, as it may be susceptible to corrosion in highly saline or humid coastal climates.

FAQs
Do I need to use a wall plug with these?
No, the Masonmate Hex Concrete Screwbolt is designed to tap directly into the masonry, eliminating the need for separate wall plugs.
Can these be used outdoors?
They are suitable for sheltered outdoor areas, but the zinc-plated finish is not designed for permanent exposure to harsh weather or coastal salt environments.
What size drill bit should I use?
Always use a masonry drill bit that matches the manufacturer-specified diameter for the particular screwbolt size you are using.
Can I remove the bolt once installed?
Yes, these screwbolts can be unscrewed, though they are primarily intended for permanent anchoring.
Are these bolts reusable?
While they can be unscrewed, it is generally recommended to use new bolts for critical structural applications to ensure thread integrity.
Troubleshooting
Bolt spins in the hole without gripping
The drill hole is likely too large or the masonry is crumbly. Use a smaller drill bit or move to a sounder section of the material.
Bolt snaps during installation
This often occurs due to excessive torque or insufficient hole depth. Ensure the hole is at least 10mm deeper than the bolt length.
Pros and Cons
Pros
- No wall plugs or plastic anchors required
- Easy to remove and adjust if necessary
- High load-bearing capacity
- Compatible with a wide range of masonry materials
Cons
- Not suitable for extreme marine or corrosive environments
- Requires specific drill bit sizing for optimal bite
- Single-use if thread is stripped during over-torquing
Setup, Compatibility & Care
To ensure maximum holding power, always use the correct diameter masonry drill bit for the specific screwbolt size. After drilling, ensure the hole is clear of loose debris by blowing it out with compressed air or a brush. Avoid over-tightening with an impact driver, as this can damage the masonry substrate and strip the bolt's threads. For long-term care in sheltered exterior use, periodic inspection for surface rust is recommended; if rust appears, a light application of a protective sealant can preserve the bolt's longevity.
