9 Font anchor bolts usually refer to 9 Font anchor footing bolts, which are used in construction and engineering to attach structural or non-structural elements to concrete. These anchor bolts can be either pre-installed or post-installed, depending on construction time and design requirements.

Material: including carbon steel, alloy steel, stainless steel (such as 304, 316, 316L, etc.) and other materials, the specific selection depends on the working environment and application requirements.

Grade: The product grade is different mechanical properties grade (such as 4.8 grade, 8.8 grade, 10.9 grade,A2-70, etc.), these grades reflect the tensile strength, yield strength and other mechanical properties of the bolt. Different grades are suitable for different load bearing requirements and working environments.

Advantage:

High load carrying capacity: Anchor bolts are capable of transmitting different types of loads, including tensile and shear forces, ensuring structural stability and safety.Suitable for old and new structures: Whether it is a new construction or the reinforcement or renovation of an existing structure, anchor bolts provide an effective connection solution.Easy to install: Rear-mounted anchor bolts are particularly convenient as they can be installed on any existing concrete surface without damaging the existing structure.Removability: Some types of anchor bolts, such as those utilizing high-strength friction grip bolts, can be disassembled, which is useful for applications requiring reversible connections.

Scope of 

application

Cast-in anchors: Installed in place before the concrete is poured, they are suitable for applications with high forces, such as attaching steel columns to reinforced concrete foundations.

Post-installed anchors: Usually installed into existing concrete surfaces by drilling holes, also known as expansion bolts or chemical anchors, transferring loads by direct bearing or friction.
