Description
Self-tapping masonry anchors for direct fixing into suitable concrete, brick and stone. Samac ZYP hex-head Thunderbolts cut their own thread into a correctly drilled hole, giving a strong removable mechanical fixing without a separate expansion plug.
Which size do I need?
Choose the diameter and length to suit the fixture thickness and required embedment. The stocked boxed options below range from M8 to M12. Larger diameters generally suit heavier fixing duties, but the substrate and required load must determine the final choice.
Before buying
Check the substrate, required hole depth, fixture thickness and drill diameter for the exact size. Load suitability depends on the base material and installation, so do not select purely by screw length.
