Part number
Notes from the standard
- Dash number: thread size (2 = 8-32, 3 = 10-32), then grip in sixteenths of an inch.
- The grip of -3-9 is not given legibly in the listing; it is left blank.
- Part number written as the listing writes it; the standard governs the exact format.
- Approved data governs. Use the screw the SRM, drawing or IPC calls for.
