Technical Information - Head Style, Length & Diameter Reference

There is some technical information that must be considered when using Tapcon® concrete screws. Concrete screws are cold-formed fasteners with twin-lead threads and one nail point tip. These twin threads can cut into the base material while tapping the concrete, brick, or block. A concrete screw can be bought in a variety of sizes ranging from 1-3/4" to 4" depending on the head shape. When using these screws, one has three finishing options- Stalgard coating, stainless steel or white paint.
