Concrete Bolts
Concrete bolts are heavy-duty masonry anchors designed for fast, reliable fixing into concrete, brick and block without the faff of sleeves and expansion shields. Reisser Concrete Bolts use a high-strength steel body and a cutting high/low thread that bites into the substrate, giving excellent pull-out resistance and a secure, non-expanding fixing in solid materials.
Each concrete bolt features a hex head for use with standard spanners and sockets, plus cutting ribs at the tip to help the bolt start cleanly and reduce splitting at the surface. A tough yellow tropicalised coating improves corrosion resistance on site, so whether you’re fixing brackets, plates, channels or frames, a Reisser concrete bolt gives you a dependable anchor that can be removed and refitted in the same hole if needed.

Concrete Bolts FAQs
What are concrete bolts?
Concrete bolts are specialist masonry fixings that cut their own thread into pre-drilled holes in concrete, brick or block. They provide a secure, non-expanding anchor without the need for separate plugs or sleeves.
Do concrete bolts need wall plugs?
No. Concrete bolts are designed to be used without wall plugs. You drill the specified hole diameter, clear the dust and drive the bolt directly into the base material.
Are concrete bolts better than traditional through bolts?
It depends on the job. Concrete bolts are non-expanding, so they put less stress on the base material and can often be used closer to edges. They are also easier to remove and re-fit. Expansion anchors may still be preferred for certain heavy-duty or cracked concrete applications.
Can concrete bolts be removed and reused?
In many cases, yes. One advantage of concrete bolts is that they can be removed to adjust or replace the fixture. As always, check the condition of both the bolt and the hole before reusing.
Can concrete bolts be used outdoors?
Yes, provided you choose concrete bolts with a suitable corrosion-resistant coating or material for the environment. For harsh or coastal conditions, consider higher-spec corrosion protection or stainless options where available.
What drill bit do I need for concrete bolts?
Use a quality masonry drill bit in the diameter recommended by the concrete bolt manufacturer. Drilling the correct size hole and clearing out dust is essential for performance.
