Review on Eagle 5416C 16 Inch Galvanized Staples by Shane Schobinger

These are regular staples of the size listed. . For internal use, staples of a certain size are all you could ask for: they work like staples. , in the photo the dimensions are reversed. 5416C is the Durofast number for a 3/16" bit, 1/2" length, 20 gauge wire shackle. B&C follows the Durofast numbering. The first two applications mentioned in the description are roofing felt and home foil. It is further noted that they are recommended for indoor use, meaning you should not rely on them as roofing material on roofs or to wrap around a house as both are designed for outdoor use. I would stick with use cases where the staples are not exposed to outside moisture. Eventually they will rust and fail.
