What is the recommended rule of thumb for the spacing between concrete fasteners?

The recommended rule of thumb for the spacing between concrete fasteners—specifically, 10 anchor diameters—ensures optimal load distribution and structural integrity. This guideline is based on best practices for avoiding excessive stress concentrations that can lead to failure in concrete substrates.

By spacing fasteners at this distance, you help mitigate issues such as splitting or cracking in the concrete, which can result from placing fasteners too close together. Additionally, this spacing allows for adequate shear resistance and improved overall anchoring performance, ensuring that the fasteners have enough area to engage effectively with the concrete, thereby supporting the loads imposed on them securely.

In contrast, other spacing options might not provide the same level of safety and stability. For example, a smaller spacing could lead to compromised integrity and increased risk of fastener failure under loads. Therefore, adhering to the recommended spacing of 10 anchor diameters is crucial for ensuring the reliability and effectiveness of concrete fastenings.
