In machine installation, which component is primarily used to secure units to the foundation?

In machine installation, the component primarily used to secure units to the foundation is the hold-down bolt. Hold-down bolts are specifically designed to create a strong mechanical connection between the machine and the foundation, effectively preventing any movement that could disrupt the operation of the machinery. These bolts are crucial in maintaining alignment and stability, especially in applications involving heavy machinery or high vibration environments.

While anchor bolts and hold-down screws may also contribute to securing equipment, they serve different purposes or are used in different contexts. Anchor bolts are often used in concrete to provide a strong attachment point, while hold-down screws may be suitable for lighter applications or temporary setups. However, for the specific task of securing machinery to a foundation in a robust manner, hold-down bolts are the most effective choice. This differentiation helps clarify why they are considered the primary means for this function in machine installation.
