Part number
Notes from the standard
- Alloy steel: dash, thread code, length in sixteenths, then P. Corrosion-resistant steel: C before the thread code.
- H in the dash marks the drilled head (safety-wire hole); no H, undrilled.
- For .1900-32 drilled corrosion-resistant screws the listing prints the same numbers as the undrilled ones; they are not repeated here.
- 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.
