Nissan Engineering Section (N.E.S.) specified six- to nine-digit Part Number formats for bolts and screws and other small hardware. During the 1970s these numbers were replaced by regular 10 digit Nissan Part Numbers.
Overview
Also See: Nissan Part Numbers
NES hardware parts originally used this six-digit format:
Type + Kind + dimensions (d) + length (L)
t-kddLL or t-kkdLL e.g: 1-10612
In the mid 1960s, the digit '8' was added to the beginning:
81-10612
Example:
- 81-10612 BOLT, fixing timing chain tensioner support [B10 model]
- Part: 81: Hexagon bolt
- Kind: 1= Low carbon steel
- Dimension: 06=6mm diameter thread
- Length: 12=12mm
Example:
- 9-16114 WASHER-lock to fix timing chain tensioner [410 model]
- New number would be 89-16114
- Part-Kind: 9-16: Washer, Tooth-lock
- Shape & material: 1=Spring-lock medium thickness
- Dimension: 14=14mm
