National Concrete Accessories offers concrete screws, in both hex and Philips head, and a selection of general construction screws in many different diameters and lengths.
Self-drilling screws like the Philips head concrete screw are engineered for consistent quality and speed. They are cold formed with rolled thread for superior strength, and fast drilling performance in metal base materials. Hex head screw design is common in applications where the head of the fastener is intended to be above the surface of the material being fastened.
