63mm long with 10mm pad. Gluing Hints for Metal Findings Whenever possible, use a file to roughen smooth surfaces. This gives a stronger grip. Clean both surfaces to be joined. We recommend using isopropyl alcohol and a cotton swab in a well-ventilated area. Why is it so important to clean the surfaces? During the manufacturing process, metal findings are coated with oil. They are degreased, but normally still have a small amount of oil left on the surface. Follow each adhesive's directions carefully when using. It's best if you can provide a dry, dust-free, well-ventilated environment when gluing. This helps assure a secure bond. Extreme temperatures might affect the drying time. Store all adhesives in a cool place.
