What component provides support to the weight of the machine set directly to the floor and screws into threaded holes in the machine base?

The component that provides support to the weight of the machine set directly on the floor and screws into threaded holes in the machine base is known as a leveling screw. Leveling screws are designed to adjust the height of machinery to ensure they are properly aligned and leveled during installation. This adjustment is crucial for the proper operation of the machinery, as it prevents misalignment and potential wear or damage during operation.

Leveling screws not only support the machine's weight, but they also allow for fine adjustments in height. This is beneficial in compensating for uneven surfaces or for setting the machine to achieve optimal performance specifications. By screwing into the threaded holes in the base, they provide a secure and stable connection to the floor, ensuring that the machine remains stationary during use.

Other components mentioned may not fulfill the same specific role as leveling screws. For example, anchor bolts are typically used for securing larger equipment or structures to their foundations rather than providing subtle adjustments. Hold-down bolts can also be used for similar purposes as anchor bolts but do not specifically relate to adjusting the level of a machine. Leveling bolts may seem similar to leveling screws, yet leveling bolts often refer to a different design or mechanism not aligned with the precise function of height adjustment in this context.
