Riley rigging screws are 100% stainless steel in construction. The bodies are spin tapered for maximu strength and smoothness of finish; the threads are precision cut to ISO Metric specifications. Rigging screws with swage ends are now produced to MILSPEC specifications, for compatibility with modern swaging equipment. The hollow-tube construction of these fittings makes them substantially lighter than brass- or bronze-bodies equivilants (up to 50% in some cases).
Riley Rigging Screws are the perfect choice for weight conscious riggers.
