series question about BOLTS

Hiya guys,

right, just need to know what the most common sized nut and bolts are on a series land rover,

im just sort of rebuilding mine and wanted to go out and get a dollap of nuts and bolts, but not sure what to get.

all this M6 M8 confuses me, why cant they sell them by the size of spanner required to do em up. id know where i was then,

Aha - first problem. I doubt you'll find any other vehicle with as much of an assortment of different threads and sizes as a series Landrover. Depending on the year the will have a mixture of some or all of the following: BSF, Whitworth, UNF, UNC and metric. In accordance with Murphy's law, the commonest size on *your* Landrover is the one you haven't got a spanner for.

2nd problem - most of the ones you'll need for rebuilding are likely to be specialised fasteners anyway (door hinge bolts, etc) so you'll probably end up buying them "on demand" when you need them. Quite apart from which, bolts are bloody expensive - you probably won't want to have a lot of money tied up in bolts on the off chance you may need them.

Because bolt size and spanner size don't always correlate eg an M8 bolt commonly has either a 12mm (JIS) or 13mm (ISO) head. Also the thread pitch can vary - "normal" M8 is M8x1.25mm, but 1.00mm is also used.

Because the heads are not always the same size for the same size of thread.

In general......... M3 = 5.5mm spanner M4 = 7mm spanner M5 = 8mm spanner M6 = 10mm spanner M8 = 13mm spanner M10= 17mm spanner M12= 19mm spanner M16= 24mm spanner

The japs tend to use smaller a/f sizes for the same size thread.

But, all this talk of M.etc will be irrelevant if you are building a series, as you will be into UNC/UNF and whitworth.

The whitworth system is far simpler, i.e. you tighten a 1/4 whit bolt with a

1/4 whit spanner!

On or around Sat, 07 Aug 2004 23:50:28 +0100, Andy enlightened us thusly:

I think you'll find that most of the bolts on a series are (meant to be) pre-metric, specially if it's an old one.

UNF and UNC, for the most part. You'll find plenty of 1/4" UNF and 5/16" UNF on the bodywork, even on early 90/110s there are still some. Most of the bodywork ones are about 1" long. some are shorter, some longer.

common UNF/UNC sizes: thread head a/f

1/4" 7/16" 5/16" 1/2" 3/8" 9/16" 7/16" 5/8" 1/2" 11/16" 9/16" 3/4"

common metric sizes: thread head ISO other head - often with captive "washer"

6mm 10mm 8mm those have a name, but I've 8mm 13mm 10mm forgotten it again. 10mm 17mm 14mm 12mm 19mm 17mm

but they're not all guranteed to have the same size heads - sometimes, as well, you'll find a different size nut. all sorts of funny-sized heads/nuts on the 300 TDi, including quite a number of 15mm a/f on 10mm threads.

Probably 3.7mm Whitworth...

Seriously, the series construction was in the era of Imperial bolts, and a lot of them were Whitworth threads. In a lot of places a metric nut and bolt would be fine. But be consistent. Don't have three metric and four Whitworth holding the wing on.

(And the lens-mount thread on old Leica cameras is apparently Whitworth profile, Imperial pitch, and metric diameter...)

My father tells me they shifted the relationship a step during WW2, and really old Whitworths have a bigger head. I ought to ask the Vicar, his steam engines are old enough for that to crop up.

I have a set of metric and imperial sockets, when one does not fit the other does, and when none fit the nut is rounded.

When I put bolts back in I use whatever fits in the hole and sometimes with a bloody big washer.

Time for the gas spanner!

But the Leica thread became a classic for compact cameras, especially when the cheap Russian Imitations flooded the market.

Same could be said for the Pentax 42mm thread that had a long hold until they eventually succumbed and went bayonet.

I still say from the latest digital Pentax to any of the older post 42 mm thread varieties you have access to the widest set of lenses available, as even the digital body can take the old screw threads with an adaptor.

As for versatility I like the K1000 a sort of series go anywhere Pentax :)

whoops that is totally OT

The message from Andy contains these words:

Look in mags for LR fasteners, bite the bullet pay the price and get a fully labled seperately bagged set of nuts bolts washers etc to do the job you set out to do. Amazing how it improves life, if not the wallet, but then my local supplier charges UKP 1 to 5 for a pack of 1/2 doz nuts and bolts depending on size, and the last time I used a major distributor "Lamberts" it was minimum order 500 .

My first decent SLR camera, that was. I won a few competitions with one. I still have an excellent condition K1000 and it's predecessor the Spotmatic F.

Mine too.

I never entered any, but some of my best photos were taken with it.

Sold mine, and wish I hadn't. Dad had a Spotmatic, and my Mum GAVE IT AWAY to a relative who expressed a vague interest in it, when he died. I was completely gutted. By the time I found out, he had lost it, or sold it, or something.

A "Series" camera - I like it.

Actually, while Whitworth were used to some extent, most of the body bolts (which is what you are mainly talking about here) on Series one were BSF, or BA in the smaller sizes. The BSF gradually changed through the early sixties to UNF, and by the end of Series three production some metric sizes were creeping in (But my 86 110 still has a lot of UNF).

Probably the most common sizes are 1/4" UNF in 1" and 1 1/2" lengths, and

5/16" UNF in 1 1/2" and 2" lengths, and 4 and 6 BA 1/2" or 3/4" long. In Series 1 (+S2 & early S2a) the UNF would have been BSF. All body bolts and nuts should be galvanised (not zinc plated) or, for Series 1 (early at least) Sherardized - which is virtually unobtainable today.

Many Landrover owners replace these with metric sizes, and it is up to you whether you do this. Some use stainless steel, but this must be done with caution, avoiding electrical contact between the alloy body panels and Stainless steel. In any case, use anti-seize compound in assembly.

The Fed-2 is quite good.

Check my brother's photo site, and the Ely cathedral pictures, at jfbell20.fotopages.com -- I think he used his Fed for that, a fifties design, while the lens is a piece of 21st Century kit.

I have an old spotmatic too but the meter is none too reliable these days. The K1000 though goes on for ever, I also like the ME supers, nice and compact. Olympus were the original compact SLR and then Pentax made a rather unsucessful 110 SLR of all things, but now SLR's have got bigger and bulkier again. Why Nikons had such a bulky motordrive I'll never know, completely over the top but at the time it marked out the press photographer, (who seem to have gone over to Canons these days, the fickleness of fashion)

The SLR 110 was a superb camera - a real camera, but with a compact film format and it really did fit in a pocket. Results were suprisingly good, but film was limited to tourist-fodder stuff. No slide film and no really slow or fast stuff.

I moved from Pentax (I used to have a Super A and an LX) a few years back to an EOS. Far more useable than most Nikon's, but probably lacking that nth degree of robustness.

The best pictures I ever took were with my (original) Olympus Trip. A cracking lens, easy to use and somehow much better than any other camera I've had since. I think it's because there is only one thing to think about - i.e. what you are pointing it at.

One point about SLR's, which also applies to Series Land Rovers, is that they have to be used. My Dad has one of every Pentax SLR ever made up to the mid 80's when it all went wrong (a strange thing to collect, but there you are). We were going to take a couple of Spotmatics on a trip just for nostalgias sake and had to abandon the idea. The shutters had all siezed slightly - not enough to lock solid, but enough for the rear curtain to lag behind significantly.

I think it was originally the Contax then Practica 42mm thread and was adopted by Pentax. I used to have a Practica, a bit heavy but an excellent SLR as were the Practicar and CZ Jena lenses. Unfortunately the lens mounting did not survive the high deceleration of a motorbike crash.

The broken Practica was replaced by an Olympus OM2N, an excellent and very lightweight SLR that is still going strong 23 years later. I'm tempted by a digital SLR but they are so big to say nothing of expensive.
