Unique Features

One fixing for all substrates. Available in a wide range of head styles, lengths and diameters. Thread gives secure grip over full embedment. 30 degree helix angle for fast insertion with power or hand tools (eg. 3 turns=40mm embedment on 8mm). Wide pitch producing high strength grip without distressing surrounding substrate. Deep thread engagement results in high performance. No expansion provides close to the edge fixing ability. Self tapping of thread into substrate allows for removal and replacement.

Screwbolt high strength shallow embedment ability replaces all common sleeve and resin anchors, does not turn in the hole, fixes instantly, has a full range of head styles, can be removed and refitted close to the edge fixing for all substrates, high speed installation, cuts its own thread, neat appearance.

High Strength: Screwbolt's high shear and tensile strength exceeds the performance of conventional anchors. In many situations, Screwbolt will enable the sleeve-anchor user to reduce fastener diameterand embedment depth whilst retaining designed joint strength.

Shallow embedment ability: Screwbolt provides higher strength at lower embedment depth than conventional anchors. This means shallower holes, hence less drill wear, less chance of striking reinforced steel and faster drilling.

Replaces all common sleeve and resin anchors: Screwbolt is stronger than a sleeve anchor and just as quick an install. Screwbolt has the close to edge performance of a resin anchor without the time and cost disadvantages.

Neat appearance: Screwbolt has a bolt head, rather than a nut with bolt sticking through. This not only looks better, bus is much safer as well. It completely eliminates the need to grind off excess stud length from a conventional anchor.

No turning in the hole: Screwbolt is not a friction device, therefore you never have the old sleeve anchor problem of the fastener turning rather than expanding.

Instant fix: Screwbolt delivers immediate strength. There is no waiting time, unlike resin anchors.

Full range of head styles: Screwbolt has a head style for every situation, including tamper-resistant security applications.

Can be removed and refitted: Screwbolt can be unscrewed and removed, leaving nothing but the hole. If necessary, the Screwbolt can then be re-inserted into the same hole with no loss of strength.

Close to the edge fixing: Screwbolt is not an expanding anchor, therefore it can be placed close to the edges and corners in the brick and concrete without damaging the substrate.

Single fixing for all substrates: Screwbolt will function in virtually all masonry substrates, as well as wood. This eliminates the need for designers and installers to change fasteners in different areas of the same job, making it easier during the construction phase and ensuring consistency of appearance forever.

High speed installation: Screwbolt's 30 degree helix angle means very fast insertion whether hand or power tools are used.
