Nylon anchor 5mm by 40mm. Will fasten materials up to 13mm thick. These are ideal for fixing light to medium fixtures and fittings to masonry, like concrete or brick. To use simply drill a hole of the same diameter as the anchor using an appropriate masonry drill, insert the anchor and nail the pin down. For heavier installations requiring more strength, steel concrete anchors are a better option. Use a masonry drill bit such as one of
these.
