Screw Bolt Contractor CSK 8 x 100mm - Carton 200

Concrete screw bolts are strong anchors for concrete and masonry that have helical threads that, when tightened, allow the bolt to cut its own thread in the concrete and masonry. Since these anchors don't expand and no plugs are needed, they are perfect for use in concrete and masonry where cracking may be an issue. For internal and external bolting and fastening of engineering and construction components where authorised anchors might not be needed, our Galvanised Countersunk range is made to provide a flush finish and an unobtrusive, non-trip hazard anchoring option. These are frequently used to secure timber battens, pool fence spigots, and other fixtures that need a flat countersunk finish.
