Expansion anchors are designed to expand when the resin cures, providing a strong hold in soft or friable substrates such as concrete or masonry. Plug anchors, on the other hand, rely on friction to hold the blockwork in place and are suitable for harder substrates such as brick or stone. Screw anchors are similar to plug anchors but have a threaded shank that allows them to be tightened to provide a more secure hold Screw anchors are similar to plug anchors but have a threaded shank that allows them to be tightened to provide a more secure hold Screw anchors are similar to plug anchors but have a threaded shank that allows them to be tightened to provide a more secure hold Screw anchors are similar to plug anchors but have a threaded shank that allows them to be tightened to provide a more secure holdresin anchors for blockwork.
