3. Ease of Installation Although the 4PCS configuration may seem complex, many anchors are designed for quick and straightforward installation. This saves time on-site, ultimately leading to reduced labor costs.

1. Variety of Sizes and Grades Hex head bolts are available in multiple sizes, lengths, and grades, making them suitable for a wide range of applications. The grading system, such as ASTM A325 or A490, denotes the tensile strength of the bolt, which is crucial for determining its load-bearing capacity.

The choice of materials in bolt construction is paramount as it directly influences the strength and durability of the component. Common materials used for bolts include high-carbon steel, stainless steel, and alloy steel, each offering different mechanical properties to suit specific environments. For example, stainless steel bolts exhibit excellent corrosion resistance, making them ideal for applications in maritime environments and industries that handle corrosive substances. In contrast, high-carbon steel bolts offer enhanced tensile strength, which can be critical for high-stress applications.

1. Dimensions The M20 foundation bolt has a diameter of 20 mm and typically comes in various lengths, depending on the required application. The length can range from 50 mm to over 200 mm, and it’s essential to choose a length that suits the thickness of the material being anchored.
