What is an essential material that can improve the holding strength of masonry fasteners?

Steel rebar is an essential material that significantly enhances the holding strength of masonry fasteners. When embedded in masonry, steel rebar provides additional tensile strength and stability. This is particularly important in structural applications where the fasteners need to resist forces that can pull or push against the masonry material.

Masonry alone may not possess sufficient tensile strength to hold fasteners securely over time, especially in environments with fluctuations in temperature, moisture, or applied loads. By integrating steel rebar, the fasteners can achieve a much better grip, significantly reducing the risk of failure.

While options like wood, plastic, and aluminum serve various purposes, they do not provide the same structural reinforcement as steel rebar in the context of masonry fasteners. Wood may be used in some fastener applications but is not inherently designed to enhance masonry strength. Plastic and aluminum, while lightweight, lack the necessary rigidity and strength to improve masonry fastening effectively.
