System allows simple creation and look-up of complex PIN numbers and then automatically produces physical standard fasteners in virtually any native CAD format. In June 2005, the American Society of Mechanical Engineers (ASME) published the new B18.24-2004 Part Identifying Number (PIN) Code System Standard for B18 Fastener Products. The new B18.24 defines PIN codes for over 630 different types of fasteners including screws, nuts, bolts, washers, pins/dowels, keys, retaining rings, rivets and SEMS (screw and washer assemblies). The PINs used in the standard have been changed from the 21-digit system used in previous versions to the new 18-digit format, without any loss of information. This new B18.24 now replaces the existing B18.24.2 and B18.24.3 standards.
