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 a six-digit format:

Type + Kind + dimensions (d) + length (L)

  t-kddLL or t-kkdLL
  e.g: 1-10612

Around 1968, the digit '8' was added to the beginning:

 81-10612

Finally in the early 1970s they transformed into Nissan standard 10 digit numbers, by adding a 0 to the beginning and two numbers to the end:

 08110-612xx

Example:

81-10612 BOLT, fixing timing chain tensioner support [B10 model]
- Part: 81: Hexagon bolt
- Kind: 11= 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

Example: B10 steering column cover screw

83-30414-1
33= Machine screw, Oval head
04= 4mm diameter
14= 14mm length
1= Zinc cadmium coated

Example: B110 steering column cover screw

08330-41410
- 33=Machine screw, Oval head
- 04= 4mm diameter
- 14= 14mm length
- 1= Zinc cadmium coated
- 0= filler to complete ten digits

Metric

Nissan models use mostly British threads until January 1967, when in the middle of the month they adopted JIS metric standards across the board, starting with the R16, H20 and H30 engines. Thereafter the metric system was "adopted for all the screw threads of engine, chassis and body of Nissan's vehicle when:"

1. Model is change.
2. New unit is adopted.
3. New model is produced.

Although some parts still remained Standard threads (e.g. R16 cylinder head bolts).

For example, 1200 wheels are still 12" by 4" with a 4.5" PCD, as befitting their English ties building Austin vehicles.
