What can masonry fasteners be used for?
There are two categories of masonry fasteners commonly used: The first is the self-drilled fastener which works by cutting threads into the concrete/brick or block. These can be used to mount electrical junction boxes, furring strips, HVAC strapping, exterior insulation systems, plywood backer boards, etc. The second type is the mechanical fastener inserted into a predrilled hole. This type of anchor provides a larger bearing surface than just the threads in the self-drilling fastener and can be used to mount heavier items such as shutters, sheet metal flashings, railings, and screened porch or pool enclosures.
