High-quality, Economy Self-Adhesive Fasteners are a sturdy choice, helping you economize on cost without sacrificing quality. Just peel and stick one inside of a file folder to bind loose papers. Fasteners are 2-3/4” from prong to prong, with a 1” capacity. They're permanent, creating a strong seal, which means that when you peel and stick them, they're not coming unstuck. Fasteners can be used with a compressor (70014) for an even more secure hold (sold separately). These fasteners give you the strength of brown enameled steel construction, made to stand the test of time. Coined edges make them smooth and safe to handle. A box of 100 fasteners is sure to keep your papers secure for a long time to come.
