What are Hexagon Concrete Screws?

The Thunderbolt™ Self Tapping Masonry Anchor is used for fastening into substrates such as stone, concrete and concrete block, amongst other masonry materials. This all-metal Hex Head fastener cuts its own thread into the substrate during installation, without expansion stress.

As a result, this specialist type of self tapping concrete screws are often chosen for close to edge applications.

For a variant fitted with a Flange head, to provide greater load distribution, please see our range of Metric Flanged Hexagon Masonry Anchors.

Unlike other screws for brick, Thunderbolt Masonry Anchors are designed to be a one-piece, non-expanding anchor, meaning installation can be achieved without the need for a wall plug or resin.

CE Marked & ETA Certified Masonry Screws.

For safety critical applications, or for installations where there is a legal requirement, Accu can also supply ETA evaluated and CE marked Hex Head Thunderbolt self tapping Masonry Anchors.

Materials.

Hexagon Head Masonry Anchors are manufactured from Steel in a Yellow Zinc Plated finish as standard. A Galvanised finish is also available for added corrosion resistance suited for use in harsher environments, such as industrial applications or in marine and coastal locations.
