Part number
What each code means
| Part | Meaning |
|---|---|
| Format | ASNA0082{prot}<dash> |
| - | Prot: Protective material code; shown as a hyphen in the work card example |
| Example | ASNA0082-402 — Diameter identification 4 (6.3 mm), grip identification 02 (2.39-3.96 mm thickness to be assembled) |
Notes from the standard
- Hexagon-head version; all five diameters are listed for grips 01 to 09.
- Part number structure per the work card: standard number, protective material code, one-digit diameter identification (2 to 6), two-digit grip identification (01 to 09). The work card example also shows a bracketed type letter, (W), whose meaning it does not explain.
- Diameter identifications 2 to 6 were matched to the Ø column by the order of the work-card tables; confirm against the standard before ordering.
- The work card checks grip thickness with grip gauge LFVLG-1 and installs with hand wrenches (series 718/729/730/731) or a pneumatic tool; the threaded rod is pulled until it breaks off.
