The Beadsmith Crimp Tubes can be used with jewelry cable and flexible wire. This package comes with crimps, that when crimped properly, are made to look more like a small spacer bead, so your finished product looks perfect. These are very easy to use. The end of the beading wire is passed through a crimp; through a loop on your clasp, or other findings; passed back through the crimp & then drawn taut. To use these properly, you should also use flat nose pliers or crimping pliers. This will allow you to clamp the crimp or fold it onto the wire to hold it in place. The crimp will also act a stopper to prevent your beads from moving around. The crimps are consistent & uniform in shape and size, with no sharp edges. That means no more snagging your sleeves & ruining your clothes! Crimp tubes are often preferred over crimp beads. They are often stronger & more durable. Because the inside of a crimp tube tends to have more space inside, they grip the wire better, providing a more secure crimp. To prevent breakage, and wonky looking beads, determine the best size wire for your crimps. 1mm is great for thinner wire, such as .007-014, 2mm is ideal for medium .019 strands & 3mm is better for the heavier cables. If your crimps are breaking, you probably have too much extra space inside. We suggest using a larger diameter of wire or use a smaller diameter crimp bead.
