When a machine is described as bolt-bound, it means that it cannot move sideways due to bolt hole clearance. This condition typically occurs when the position of the bolts that secure the machine to its foundation or mounting surface restricts its lateral (side-to-side) movement.

In machinery and maintenance terminology, bolt-bound situations arise when components of a machine are more tightly constrained than necessary, often leading to operational issues. Specifically, if the holes where bolts are placed do not allow for adequate clearance, the machine will be unresponsive to any attempts to shift it in those lateral directions. This can cause stress on the machine and its components, potentially leading to premature wear or failure.

Understanding this term is crucial for proper maintenance and alignment practices, ensuring that equipment operates efficiently and safely without the hindrances imposed by improperly secured or positioned bolts.
