These fasteners are made in different lengths and widths. The width varies from 5/8 inch to 1-1/8 inches, and the length ranges from 1/4 to 3/4 inch. Corrugated fasteners are used to fasten parallel boards together. Typical uses for corrugated fasteners are in mitered corners, butt joints, and end joints.
