Notes from the standard
- The first characters of the dash give the diameter (08 = .164, 3 = .200, 4 = .260); L after them marks the self-locking feature, then the grip dash.
- The listing does not state material or finish, nor the thread size.
- Part numbers are shown as the basic number followed by the dash; the listing does not show a separator, so confirm the format in the standard.
- The listing lists the same diameters, grips and dash numbers as for NAS1750 and does not state how it differs from NAS1669.
- Approved data governs. Use the fastener the SRM, drawing or IPC calls for.
