What are Anchor Screw Bolts? | Product Showcase

In this video, we cover Anchor Screw Bolts which are a form of Screw Bolt.

These bolts have a self-tapping thread that effectively creates a nut to the bolt within the substrate itself, holding it firm. Self-tapping is a tried and tested process with wood and metals that can also now be applied to other materials such as brick and stone.

I'm glad I found this video. Now I definitely know to drill 2mm less than the anchor screw bolts. Another company told me to drill a 5mm hole in the stone for my 5mm anchor bolts which I thought was odd.
