holdfast
Danh từ
Số nhiều: holdfasts

In biological contexts, this term describes a specialized anchoring organ. It is distinct from a true root because it does not absorb nutrients or water from the soil; its sole function is mechanical attachment to a hard surface, such as a rock or shell.

In mechanical engineering, the term refers to a clamping tool or fixture. It carries a connotation of absolute stability and rigidity, emphasizing the prevention of movement during high-pressure operations like drilling or milling.
