Hi,

Can anyone suggest a source of these:



Number 4 on here:



I think the thread is #10 UNF.

Does anyone know if these are a 'thing' available in the wider world or are they just something SAAB used to hold headlights in place...?

Cheers

Gareth

Hi Dirtbiker ! Good question, this is a turned part. I work in industry and will check if some of our suppliers provide that kind of parts.
I'll let you know.

A quick Google search for "knurled nuts" and "thumb nuts" gave quite a few hits for metric sizes but this was the closest in UNF - https://www.mscdirect.com/product/details/00256875 .

The 'Type Bas' are a closer match to the originals, but again metric thread.

Just found these in the spares stash, don't think I will ever get round to using them. I can't be certain they are what you're after, but they look about right.
I can send these down to you for you to see if they're right. Are you still at same address?

PYM35 and Deggsie - thanks for your help! Knowing what to look for was the problem here - never come across the term 'thumbnuts' before...

Right, I have a plan. I am going to order some of these https://www.ebay.co.uk/itm/M5-Thread-Carbon-Steel-Zinc-Coated-Knurled-Thumb-Nuts-10pc/303127848099?hash=item4693d3e4a3:g:koUAAOSws19ZfgU9 which are M5. As they are going on here



I think I can cut an M5 thread on the new 3D printed plastic pegs. If anyone hasn't seen these pegs they are here https://www.shapeways.com/product/HUN7HN5JN/saab-96-v4-headlight-retainer-studs?optionId=62242179&li=marketplace

Digger - offer very much appreciated. Would I be able to take you up partially - could you send me one of yours. The reason is I need a set of six for the 96 and just one for the 95. The M5 ones I am going to order are larger (16mm dia) which will look fine as a set but a single large one on the 95 may bug me... Before you send it the ones on the 95 are 14mm ish diameter. Still at the same address, shame I won't see you at Swedish Day.

Thanks again for everybody's help - this forum and the collective knowledge is brilliant!

Cheers

Gareth

Hi Gareth, they do appear to be about 14mm, I'll get one in the post to you.
Very jealous of your 95 from America, I didn't realise you could buy them without rust. All the 96s I've bought were mainly rust.

Hopefully there might be Swedish Day in October. Take care

Thanks - it would be boring if we didn't get to practice our welding skills though!

Hello, Dirtbiker:
You might try the following 2:

1. Look at Saabnet.com>select Saab Bulletin Boards> scroll down & select Vintage Saab Models> type in search box: Headlight Trim Ring Screw 3D Printing>Press Search> view posting by hmssaab, dated 2/21/2014

2. Try Don Levesque at dwlgrl@comcast.com

I think each of these 2 fellows has ordered thumbnuts or may have good info on how to acquire them.

Good luck.

Digger - Thumbnut arrived. Looks perfect but haven't tried it yet as the interior of the 95 is on the bonnet - found some welding to do!
Thanks for sending it!

elanwannabe - I will have a look at those threads now, thanks!

Hi elanwannabe,

Had a look at the Saabnet thread. Turns out I had already purchased the plastic pegs from Shapeways from hmsaab. Looks like the thumbnuts are still under development but I suspect they need to be metal as the thread on the pegs is a bit roUgh and needs to be 'cut'.
I did find some UNF thumbnuts in the US but I have ordered the M5 ones from ebay and will see how I go.

Cheers

Saab P/N 7246630. Used on USA Headlights qty 6 as above. Also used on early round dash clock in Saab 95 Qty 2-48000 ChNo. and Saab 95 Fuel gauge Qty 1.
My reserve stock as below and said dash clock for ID. The thread is M5 x 080 which is very close to 3/16in UNF which is slightly smaller.
The USA headlight bezel screws are p/n 7867864.

Hi Woody,
Thanks for that - I picked up some M5 ones off ebay as they were more readily available. They seem to screw on to the reproduction plastic screws nicely although I haven't tried them on the car yet.
Cheers
