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.
Early Format
[from 520 parts catalog C-037 1965.8]
Nissan Standard Parts (N.E.S.) N.E.S. (Nissan Engineering Standard) parts consist of 6 digits, arrangement of which is, as a rule, in the following order:
Kind(1-~9-59) + Shape & Material(◯) + Nominal Dimensions(Ⓞ) + Length(Δ)
For N.E.S. Parts that have been processed surface finishing or cotter pin hole symbols showing these processings are added to the rear end.
Part Name Arrangement of Digits ------------ ------------------------ Hexagon bolt 1 ◯ Ⓞ Ⓞ Δ Δ Carriage bolt 1 ◯ Ⓞ Δ Δ Δ Stud 2 ◯ Ⓞ Ⓞ Δ Δ Machine screw 3 ◯ Ⓞ Ⓞ Δ Δ Tapping screw/Wood screw 5 ◯ Ⓞ Ⓞ Δ Δ Rivet 6 ◯ Ⓞ Ⓞ Δ Δ Hexagon nut 9 1 1 ◯ Ⓞ Ⓞ Self-lock hexagon nut 9 1 2 ◯ Ⓞ Ⓞ Miscellaneous nut 9 1 3 ◯ Ⓞ Ⓞ Washer 9 1 5 ◯ Ⓞ Ⓞ Tooth lock washer 9 1 6 ◯ Ⓞ Ⓞ Nut retainer 9 1 7 ◯ Ⓞ Ⓞ Pin & Key 9 2 0 Ⓞ Δ Δ Plug 9 3 1 ◯ Ⓞ Ⓞ Grease Nipple 9 3 2 ◯ Ⓞ Ⓞ Electric parts 9 4 ☆ ◯ Ⓞ Ⓞ Rubber parts 9 5 ☆ ◯ Ⓞ Ⓞ
NOTE: ☆ Kind, ◯ Shape & Material, Ⓞ Nominal dimension, Δ Length
2. Distinction by Alias Dimension (Mark Ⓞ)
Distinction by alias dimensions of diameter and width, and apply 2 digits next to the rear of the digit showing Shape & Material.
[Table shows each code could mean #, inch, or mm value.
Later catalogs add these notes:
1. A. B. C. D. の 4 系列の適用については別に定める。
2. スタッのドの呼び寸法の大きさに対する？？のつけ方は別に定める。
3. ？ビンにおいては？ 1 杤の？？を？？する]
3. Distinction by Length Mark (Δ)
Apply 2 digits next to the rear of those standing for Alias Dimensions. However this is not applied when the length is not necessary.
[The digits are in mm, conversion is to inches]
4. Symbols of Surface Finishing, Cotter Pin Hole
For the parts that have surface finishing or cotter pin hole, apply the following digits adding mark to the rear of the above mentioned parts number.
Surface Cotter pin hole Not processed 10 Zinc-Cadmium 1 11 Chrome coated 2 21 Copper coated 3 31 Phosphoric Acid 4 41 Brass 5 51 Copper 6 61
Overview
Also See: * Nissan Part Numbers * NES Legend
NES hardware parts originally used a six-digit format:
Type + Kind + dimensions (d) + length (L)
t-kddLL or t-kkdLL or t-kkkLL e.g: 1-10612
Surface-processed parts had suffix added e.g: 1-10612-51 or 83-30414-1
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 requiring two finish processing digits at the end:
08110-612pp
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 (M6)
- 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 machine screw
- 08330-41410
- 08=standardize hardware prefix
- 33=Machine screw, Oval head
- 04=4mm diameter (M4)
- 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.

Length Digits
長さによる区分
LL digits = Length Early form: n-nnnLL (likely to be imperial) Transition form: nn-nnnLL 1970s form: nnnnn-nLLnn (likely to be metric)
Datsun fasteners started out using imperial dimensions (British thread standard). But more and more during the 1960s Datsun used some Metric fasteners, until starting in 1967 nearly all parts were changed to metric. Lastly, the flywheel bolts changed to metric in 1973. Only the oil sender threads continued to use BPT.
Metric LL digits 04 4mm ... 95 95mm
Imperial LL digits 07 1/4 inch 10 3/8 13 1/2 16 5/8 19 3/4 22 7/8 26 1 inch 28 1-1/8 32 1-1/4 35 1-3/8 38 1-1/2 41 1-5/8 44 1-3/4 48 1-7/8 51 2 inch 54 2-1/8 57 2-1/4 64 2-1/2 70 2-3/4 76 3 inch
Suffix
For parts that have surface finishing or cotter pin hole, symbols showing these proceedings are added at the end of the part number.
Two digits mean it has a cotter pin hole. Single digit: No cotter pin hole.
