Final answer:
The statement is false; there is a standard symbol for countersink in engineering drawings. The symbol is accompanied by dimensions and 'c'sink' is also used as an abbreviation in callouts.
Step-by-step explanation:
True or false: there is no symbol for countersink, but 'c'sink' is a common abbreviation in the callout.
False. In drafting and engineering, there is indeed a standard symbol used to indicate a countersink. The symbol is a conical shape that is often accompanied by specific dimensions representing the angle and diameter of the countersink. However, it is true that 'c'sink' is a commonly used abbreviation in a callout or note to indicate a countersink requirement when specifying the need for countersunk holes on technical drawings.
