Screw Bolt – Countersunk – Thunderbolt Pro

Countersunk screw bolts are invaluable fastening solutions, boasting a one-piece design, high tensile strength, and self-tapping capabilities tailored for anchoring into masonry and concrete substrates. These versatile anchors not only provide robust fastening but also offer a flush finish to the base material, thanks to their countersunk head design. With the ability to generate low expansion forces during installation, screw bolts enable close anchor spacing and near-to-edge applications without compromising the structural integrity of the substrate. This feature makes them ideal for a wide range of projects where precision and aesthetic appeal are paramount.
