GUSEN concrete screw bolt anchors are high strength concrete and masonry screw anchors with helical threads allowing the bolt to cut it’s own thread in concrete and masonry when tightened, no plugs are required and these anchors don’t expand so they are ideal for use in masonry and concrete where cracking may be a problem.

galvanised screw bolt anchor contractor range is designed as a cost effective anchoring solution for internal and external bolting and fixing of construction and engineering components where approved anchors may not be required.

the galvanised contractor range of screw bolt anchors is a very effective, heavy duty, economical method of fastening directly into masonry and concrete.

Because of the three setting depths and the adjustability the screw is usable for a great variety of applications. The concrete screw as an expansion-force free anchor is also ideal for temporary fixings as it can be removed completely.

Due to the integral washer no additional washer is required and you save time during the installation. For higher corrosion resistance the GUSEN is available in zinc flake coating as well as stainless steel A4.
