The Blue Wave Chromed Bronze Body features a number of details that makes it the best choice for exclusive and durable rigging. The sleek, open Bronze body prevents the threads from seizing up, they are delivered with laser engraved thread size, Blue Wave logo, and side marking of the left thread. These are the rigging screws we most commonly use for swaging directly onto wire - we do not advise you to try to use them unless you have access to approved roll swage machinery.
Except on the 3mm size there is a choice of 2 sizes of rigging screw for each of wire. On 4, 5, 6 & 7mm sizes we almost always choose the larger of the 2, preferring the larger of the 2 when set against the relatively modest extra price.
