Concrete Security Screws

Concrete screws, also known as masonry screws, are designed for use in concrete, brick, and hollow block. In this way, concrete security screws provide the dual benefit of dependable, problem-free installation coupled with superior in-place performance.

Concrete Screw Products:

Torx Tamper-Resistant UltraCon Masonry Screw: This particular screw incorporates the first-class quality and simple installation benefits of an UltraCon masonry screw along with the security features of a Torx tamper-resistant fastener. The threads are twin-lead, which causes mechanical linking to the masonry. In turn, this leads to increased joint integrity.The screw’s edge cuts deeply and effortlessly, due to the sharp, high thread. Stability for accurate and quick driving is made possible by the alternating low thread. A stalegard® finish coats the screws, providing 1000 hours of top-quality resistance to salt spray with no red rust per ASTM B117.

Choosing the Appropriate Fastener Length

In general, determine the appropriate concrete security fastener length by adding the desired depth of embedment with the thickness of the screw attachment. (Note: each concrete security screw should have a recommended minimum and maximum embedment length to be used when determining fastener length. For example, the example concrete screw listed above suggests a minimum embedment length of 1″ and a maximum of 1-3/4″.) In combination the diameter of the fastener and the depth of embedment affect pullout strength. In turn, application strength requirements and safety factors should be considered when determining the depth of embedment and fastener diameter.
