The useful OEM fasteners thread

Thought it might be useful for folks to put up details of interesting and useful fasteners that they are aware of from oem manufacturers - not stuff like regular nuts and bolts that can be obtained anywhere, but particularly useful stuff thats not run of the mill.

Part number, manufacturer, price, dimensions and a photo would be useful.

I'll start

Hex-headed screw bolt with a built in washer - some kind of grey plating
Seat N 905 426 04
35p each
10mm hex head
17mm dia washer (2mm thick) - integral but loose fitting
23mm total length / 16mm threaded section
6.5mm dia threaded section

 

Good idea.

High tensile studding with unthreaded centre sections:



M6 thread
Length: 25mm approx
0.37+VAT each
N 901 752 05
OEM use: Golf 16V rocker cover
VAG use: Generic stud.

M8 thread
Length: ?mm approx
?+VAT each
N 044 514 5
OEM use: Golf 16v head exhaust studs etc
VAG use: Generic stud.

M8 thread
With integral hex ends for ease of fitting
Length: tbc
Part no: have it somewhere
Price: would be out of date
OEM use: Ford CVH exhaust manifold-to-head, 1989-1992 (possibly beyond)
VAG use: Nice wind-in stud, unique - differing from generic.

 

Countersunk allen bolts
OEM use: Mk1 Golf/Jetta door latches.
VAG use: Any flush mounted surface eg OMP Mk1 Golf sumpguard.
N 0214163
M8x32



10.9-tensile hex bolts, M10? thread
Length: 38mm under head, 11mm unthreaded
Part no: F1640024 N/STK 009267/Bolt (also found a ref 52994 F/E on last packet I bought)
Price: 1.08 plus VAT each



OEM use: Ford Escort Cosworth rear hub bolts
VAG use: for running rear stub axle spacers - click

 

Camber correction bolt for mk2/mk3/Seat etc front hub - strut

N 101 740 02

M12 bolt with 11mm plain section. No (40) on here

From a previous thread:

VAG use: compensating for short stud or sleeving through wide components.

 

OEM: VW timing belt tensioner stud kit:
M10 stud?
VAG use: Generic stud.

 

M6 - M8 stud
OEM use: 8-valve cambelt covers
VAG use: unique m6 => M8 conversion stud.
049109166



M10 - M10 stud
OEM use: Polo 084 gearboxes

M10x21 / M10x21



Longer versions available on Golf 084 gearboxes
VAG use: Generic stud with raised centre section.
084301109
M10x45 / M10x21

 

These aren`t particularly special. I can lay my hands on literally hundreds of s/s ones at work...

 

Not special as such, just useful I use them for flush sumpguard mounts.


10mm ball pin
OEM use: Mk2/3 Golf tailgate strut anchor points
VAG use: combine with socket ends and a threaded link bar of any length can be made - click
533 827 345 C
M6

 

The cambelt stud is ideal for compressing the 020 gearbox spring that is behind the output shaft to get the circlip off. Also, use a long slotted adjuster off the alternator fanbelt clamp across the top of it. Rough and ready, nut works!

 

M6 - M6 stud
Length: ~26mm, threaded sections 6mm & 10mm respectively
Part no: P V028 103 665 "N/STK 916069/AT"
Price: 3.14 plus VAT each - expensive, but handy if in low quantities/in a hurry
OEM use: TDI engine cover anchor points. Washer can be removed.
VAG use: Generic stud with 10mm blank centre section.

 

Rubber retainer & bobbins
Part nos: 1H0 129 673 B (bobbin) & 1HO 129 833 (band)
Price: not sure
OEM use: they're off my Passat airbox, but judging by the part no, I suspect they're all over Mk3s too. Scrappies must be full of them.
VAG use: retention of any item which doesn't require absolute anchoring solidl, and/or oft-removed items - by hand.

 

Self tapping bolt?
Part nos: ?
Price: not sure
OEM use: IIRC they're off Mk2s, retaing earth wires in the boot area, again scrappies must be full of them.
VAG use: just a generally useful bolt for any earth wiring purpose, with the bite it generates on tighten up.

 

Just to pull this out of an earlier post with an update:

Splined M8 stud
OEM use: Mk1 Golf/Jetta top mounts
VAG use: generic use where maintenance can be simplified, esp if access difficult / 2 pairs of hands needed. Alternative is to weld in hex bolts, but with studs, everything can be disassembled.
431 412 419
M8 x 20
(or tap them out of used ones)



Similar ones are avail from a bracket on the inlet manifold of a 16v engine (down the back). Not necessarily splined, I think they're welded at 3 points and would have to be knocked out. Part no 037 253 084 J. 22mm long.

Update

I was looking for longer versions, these ^^ being quite short at 20mm.

Nipped down the scrapyard today and top mounts are a ripe picking ground for these:



Left to right:

1) Mk1 Golf top mount, same as in first pic
2) Fiat Cinquecento front top mounts - M8 x 25 with unthreaded nose
3) Volvo 850 front top mounts - M8 x 25
4) Volvo V40 front top mounts - M10 x 18 with unthreaded nose

The Fiat ones hammer out a treat, Volvo ones need more of a belting. Needs a couple of cars to get a full set, as the threads will get damaged on some if they jam under the upper spring plate.

Some are no use whatsoever - being non-splined - instead being welded or other types of distortion fit. Typically Ford Focus and Pug 106. There's a surprise!

 

top thread guys

would it poss for you to give a brief explanation of where else you like to use the parts please?

along same lines as this

cheers

 

Grand thread, for an accountant, Blue Boy!

I picked these tractor bolts up, at the local NCF, some weeks ago. Turns out the bl00dy things are Imperial!

 

I've added in some explanations above

To be fair, a lot of it is for modified stuff where the user decides the application, but without knowing where to get the items, the user is marooned!

Dave, this is the Accountant's Revenge for all the ear ache budget grief! Saving money and time, with improved design

I did see a tractor site the other day, looking for studs. I can't remember what wasn't suitable about it, but Tractor sites well worth having an eye on.

 

great cheers Chris, very interesting

 

Ask me about how much it cost the companies I worked for, due to Accountant's cost saving exercises!

Cheap photo-copy paper, cheap design pads, cheap draughtsman's chairs, cheap and nasty Auto-Cad instead of ME10, to name but a few. All of these looked good on his two column book-keeping paper, but they would have cost the Design Department tens-of-thousands!

A few swift, but lengthy, memos, to the MD, with real world costings, soon resolved the the matters. Funnily enough, due to those memos, the relationship between myself and the Accountant kept going down-hill!

Funny Story:

Once, mrs daved and I were talking to another couple, in a pub, in Kenmare, Kerry. They were US college professors, on holiday. We got onto the subject of what, as an Engineer, made my job difficult? I explained, very loudly, they being foreign, and me being quite pi55ed at the time, it being about 9 o' the clock, that it was the Accountant, and explained why. The couple at the next table got up and left, with the posh wife saying, in her very affected English accent:

"We are leaving! He's talking about you."

EDIT: 7.28 am. Mrs daved has just read this, and veryfied that my memory is correct on the subject!

 

@ BBB

We need a new thread on the subject of: Accountants vs real 'Real World' costs!
