Philips Flat Head

Philips flat head concrete screws, widely known as "Tapcons", are screws made for screwing directly into concrete, masonry block, and brick. They feature a countersunk Philips flat head for applications when the screw needs to be mounted flush with the joining surface and a blue coating which aids in corrosion resistance. Some applications are fastening conduit and electrical fixtures to walls, anchoring hand railings, metal door frames etc. A hole is drilled to the correct diameter and the screw is fastened into place.
