Red designates the 3/8" hole size in the pull plug color system. Red is highly visible against bare metal, making it easy to confirm all plugs are installed before coating and all plugs are removed after curing. No plugs accidentally left behind in parts.

Yes. 3/8" holes appear on virtually every type of fabricated metal part, including bolt holes, dowel pin locations, sensor mounts, and fluid passages. The SPP375 is one of the most frequently ordered pull plug sizes because 3/8" holes are so widespread.
