Alloy Steel Right-Angle L-Metal Bolt M12 with Black Oxide Coating for Industrial Machinery Base Mounting

The design specifications for anchor bolts include material selection, dimensions, embedment depth and installation methods, ensuring the safety and stability of the structure.
The importance of anchor bolts
Anchor bolts are key components that connect the superstructure to the foundation, bearing the critical responsibility of transferring various loads. Proper design is the foundation for ensuring the safe and reliable operation of the structure.

Common Design Specifications
Material Selection: Anchor bolts are typically manufactured from high-strength steel, such as Q235 or Q345. In corrosive environments, materials with good corrosion resistance should be selected, or anti-corrosion measures should be implemented.
1Diameter and Length: The diameter of the bolt should be determined based on the load to be borne, the type of foundation, and the connection method. Generally, the greater the load, the larger the diameter should be. The length of the bolts must ensure sufficient penetration into the foundation to provide reliable anchoring force.
2Embedding Methods: Anchor bolts are generally embedded in concrete foundations using either the pre-embedded method or the pre-drilled hole with secondary grouting method. Direct embedding is suitable for structures such as towers, tall vessels and machinery subject to significant vibration, whilst the pre-drilled hole method is suitable for horizontal vessels and small vertical vessels, etc.
3Spacing and Arrangement: The spacing of anchor bolts should be arranged reasonably according to the structural load characteristics and installation requirements; generally, it should not be too large or too small, to ensure the structural integrity and stability.
4Installation Requirements: During installation, the tightening force of the bolts should be uniform, and tightening should only be carried out after the concrete has reached at least 75% of its design strength.
