What Can Concrete Screws Do for You?Concrete Screws or masonry screws made of stainless steel and carbon steel are ideal for use in concrete, brick or block base material. They have the following features:

flat head concrete screws. High-low threads design makes solid attachment. High tensile and pressure strength. Commonly with corrosion coating. Tested for fire safety. Easy and fast to install: drill, drive, done. No plugs needed. Removable and adjustable. Suitable for concrete, brick, natural stone, etc. Different types of head designs and surface treatment for multiple applications. Can be used close to the edges.

Different Head TypesThere are three kinds of head styles of concrete screws - flat head, pan head and slotted hex head. Comparing the different kinds of screws, the flat head and pan head concrete screws can be flush to material surface and look nice, and the slotted hex head ones are easier to drive in. So the choice depends on the location where the screw is fastened.

ApplicationConcrete Screws are very utility and are ideal for use in fastening applications. These screws come in various sizes and styles which are very easy and fast to install. Besides, concrete screws can be removed without damaging the base materials after installing. These screws can also be installed close to the edge.Different lengths allow the screws to be used in many applications including: studs, plywood, electrical boxes, and exterior insulation systems. They can also be used for fixing window or door frames manufactured from wood, plastic or metal to concrete, brick, hollow brick or man-made blocks.

Installation Steps

4 Measure the thickness of the material you will fasten to the concrete. Then choose a screw that is 1 to 1.75 inch longer than the thickness of the material.5 Choose a drill bit that is suitable for the screws. The diameter of the drill bit should be a little smaller than the screws.6 Measure the length of the screw. Then wrap the tape on the drill bit to mark the length of the screw. The tape can avoid drilling too deep in the concrete.7 Drill the hole until you reach the tape.8 Clean out the excess material from the hole with a wire brush and a vacuum.9 Set the material over the hole, and then screw the material into the concrete.
