Land Rover Nut & Bolt cross reference

Is anyone aware of a document or website that cross references Land Rover part numbers (from Parts Book) to what size / type nut or bolt it really is?
it would be great to look up a part number that is described as "nut" in the parts book and find out the size, thread pitch, class of nut or bolt.
I know the scanned documents will occasionally list the size, but not always.

I may have found an answer to my own question.
I found a post from javelinaDave from Feb 2017.

While not quite what I was looking for -- the ability to enter a LR P/N and get the details
the above website allows you to click on nut or bolt in question and the description of size is listed.

Many of the Leyland era fasteners followed a pattern that was relatively decipherable, such as..
FB108221 - Flanged Bolt 1=metric 08mm diameter 22x5=110mm long 1=yellow zinc? plated
FS108257L - Flanged Screw 1=metric 08mm diameter 25mm long 7=zinc flake/Geomet? L?
BX110076M - Bolt X=grade 10.9 1=metric 10mm diameter 07x5=35mm long 6=cadmium? M=patchlock
BT606106 - Bolt 6=UNF 06x1/16=3/8 diameter 10x1/8=1-1/4 long
NY507041L - Nyloc nut 5=UNC 07/16 diameter 04x1/8=1/2" tall?

The Series, BMW, Ford, JLR era part numbers appear to be random.

very helpful!!!
I believe this is for BSF
SH406061L. Screw Hex 4=BSF 06=6/8" 06=6/8" (although the designation shows this to be a 5/8" long bolt)

I bet that bolt was the last BSF fastener to be used on a production automobile, being used up until Defender production ended in 2016.

Looks like all the BA screws used on TDi and earlier fuel systems use the numeric Series numbering system.

The Acme bolts such as AM605066 re-use the 6 designation for UNF, but the AM is obviously Acme.

@dkemm have you made your introduction with the LRWorkshop webisite yet? Often times a bolt or nut is referenced in the description, or it can be followed to a suppliers link to get more info.

as an example, #21
I am very familiar, and use the site quite often. What I was looking for was the reference to standard sizing so that I can get items from local resources or online like McMaster. The online catalogs ‘mostly’ include the info, but not always. Having a 35yr old vehicle means bolts breaking or badly rusted - so I am addressing fasteners as I clean up components

I can relate to that. I have not tried to make a 100% as original (down to every nut and bolt exact) but I have put in orders for common sizes in bulk and just build with it that way.

yea, I did that when I did the engine swap / front portion. lots of m6 / m8, probably didnt get the lengths to the factory length. What I hate is having to buy a "bundle" of unknown sizes in a kit...much prefer to go with what I need - the link I posted above provides the size/length/pitch info but the factory part number cross reference can be a challenge. The info from erover82 in regards some part number descriptions has also been helpful.
I am getting ready to do a chassis swap - just waiting for it to arrive - and I know I am going to run into many old bolts, many I will need to grind off, etc. I am working to at least have the major known bolts, or UNF threads ready to replace with new - go grade 8 in areas of stress, SS on body panels (probably with nylon washers to prevent galvanic corrosion)

Good luck with the chassis swap, post up some pics. Its always a fun job. and right on with any sort of barrier on the SS hardware on Aluminum.

There at least used to be a supplier who would sell you a large box that had the *complete* set of nuts/bolts/fasteners used in a Series IIA for £££. Definitely the "nuclear option" for making sure that you have everything needed for your restoration.

^That being said, the Series IIA as a whole really should be availble in kit form (i.e. CKD) for hobbyists. (Too bad that I doubt this is particularly legal in many jurisdictions, even with a harvested VIN from another vehicle).
