What should be covered on one side of the assembly when marking fastener locations?

When marking fastener locations on one side of the assembly, using layout tape is considered the most appropriate choice. Layout tape is designed specifically for marking and measuring on surfaces, providing a precise way to indicate where fasteners should be placed. It typically has a straight edge and is often colored to stand out against the material, making it easier to identify the marked locations clearly and accurately.

In contrast, marker tape is generally intended for temporary labeling or marking and may not provide the same level of precision needed for proper fastener placement. Inspection tape, while useful for visual inspections, is not primarily designed for layout purposes. Lastly, adhesive tape, while it can hold materials together, does not serve the specific function of accurately marking locations for fasteners. Therefore, layout tape is the ideal choice for the task, as it emphasizes precision and clarity in the assembly process.
