3. Thermal Expansion Materials expand due to heat. When temperature variations occur, the differing rates of expansion between the anchor bolts and the material they are affixed to can create stress, leading to loosening. This is especially common in environments with extreme temperature fluctuations.

1. Structural Foundations These bolts are often embedded in concrete to anchor structural components, such as columns and beams, providing a solid base for buildings and bridges.

Anchor bolts are critical components in construction and engineering, providing essential support in securing structures to their foundations. While they are designed to withstand significant loads, loose anchor bolts can pose serious risks, leading to structural instability and safety hazards. This article will explore the causes of loose anchor bolts, their potential consequences, and effective solutions to prevent this issue.

5. Nut and Washer Compatibility When using M20 bolts, it’s crucial to pair them with corresponding nuts (usually M20 nuts) and washers. This combination ensures a secure fit and distributes the load evenly, minimizing the risk of loosening over time.
