Hollow Wall Anchors for Plasterboard

Hollow Wall Anchors for Plasterboard & Cavity Fixing

Scrooz Fasteners supplies a complete range of high-performance hollow wall anchors engineered for secure fixing into plasterboard, drywall, gyprock, and other cavity wall materials where traditional fasteners fail. Designed for medium-duty applications, these expansion anchors deform behind the wall to create a strong, vibration-resistant hold—ideal for shelving, mirrors, curtain rods, fixtures, and brackets.

Also known as plasterboard anchors, umbrella anchors, or cavity wall fixings, our anchors are made from zinc-plated steel and feature anti-rotation barbs and load-spreading legs to prevent pull-through. They are suitable for wall thicknesses from 3mm to 24mm, with size options including M4, M5, and M6. Typical working loads range from 10–20kg depending on size and substrate, making them a reliable fixing choice for both trades and DIYers.

For best results, use with our hollow wall anchor setting tool for rapid and secure expansion without twisting. Manual screw-in installation is also possible using a standard screwdriver or drill. Our auto-collapse tool increases consistency and drastically reduces installation time on repetitive tasks.
