Made from hot dip galvanised steel, the end fittings are quenched and tempered. The eyes are elongated to facilitate fitting. The length specified on the straing screws is the maximum take up of the threads. The proof load is twice the working load limit. The ultimate load is five times the WLL.
Sta Lok manufacture the ultimate riggings screws in stainless steel and bronze. They are widely used on prestige yachts and by architects. Flints can offer advice on the correct selection of these products which can be supplied roll swaged onto your wire or with fit yourself Sta Lok fittings. We can even supply wires with a left hand thread on one end and a right hand one on the other end so that the wire can be tensioned between drilled and tapped handrail posts without the need for rigging screws. If you have a project which involves unusual rigging applications we can probably help. Please phone and ask for our rigging manager.
