Screwbolts Hex Head — Self-Tapping Concrete Anchors for Concrete & Masonry | Excalibur & Serbolt Variants

Screwbolts are a fast, efficient concrete anchoring solution for tradespeople and contractors who need a secure fixing without the setup time of a resin or expansion anchor system. Self-tapping into the base material, they cut their own thread directly into concrete, masonry or pre-cast concrete beams — making them a practical choice for high-volume fixing work on site.

Available in two variants — Excalibur and Serbolt — both in hex head format, covering a wide range of thread sizes and anchor lengths to suit structural and general-purpose applications. The hex head drive provides a positive, torque-resistant installation using standard tooling.
