Which Bolts & Where From?

[danielbrookes]

Hi,

 

Recently purchased my starter kit and I'm cracking on with the build - enjoying and learning lots. I've searched but cant find the answer to this so here goes...

 

Does anyone know what bolts I need for my build, or what would be a good quantity to order? I see there are mixed bags here and I am going to order a pack: http://www.namrick.co.uk/acatalog/Home_Mixed_Packs__48.html

 

But I am not sure of the rest. Roughly does anyone have any ideas of quantities? I have the "bag of nuts and bolts" which comes with the kit but from experience, what else?

 

e.g

 

20 x M6 10mm 8.8 HT

100 x M8 30mm 8.8 HT

50 x M10 50mm 8.8 HT

 

I dont want to order loads of one size which I am not going to use and not enough of the other.

 

I've ordered a selection of M6/8/10 bolts and nylon nuts from screwfix which are stainless and I know I shouldnt be using those for anything which is important/high stress but I am not sure what else to order.

 

Thanks.

I used 2 Namrick mixed packs for my 2B....

The odd bolts I remember are the seatbelt ones which IIRC are UNF...but dont know the exact size.

You do need to have them marked again IIRC 8.8.

Seatbelt/harnesses use 7/16unf and as above must be 8.8 marked.

I found this in the IVA under seat-belt anchorages

 

"Bolts used in structural areas should be of grade 8.8 or better. Such bolts will be marked 8.8 or 12.9 on the hexagonal head, however, cap-head bolts or 7/16" ( 11mm ) UNF seat belt anchorage bolts (with an anodised finish) not marked in this way may normally be considered to be of equivalent strength. Bolts should be M8 or larger."

 

Does this mean that the UNF bolts dont need the steel grading on them?

[theduck]

Recent experiences seems to suggest they ignore that part of the rule.

ah fair enough, I was planning on replacing them regardless, just for my peace of mind. Are seatbelt harness bolts a univerally standard size then? I find it confusing that GBS will produce the car with (what i've seen so far on my build) 100% metric bolt sizes, apart from in 1 place?

[theduck]

Yeah 7/16 unf is pretty standard accross all cars.

As posted before don't use BnQ etc locate your local fastner supplier , make sure you get bolts not set screws [bolts have an unthreaded portion below the hex head, 8,8 marked minimum , never unmarked if load crical I prefer 10.8or cap heads which should be 12.2 if areliable source [ not chinese ], set screws are ok for panels etc as you will be using short ones and dont need the shank it can be a mine field so be carefull and ask lots of questions mowerman

[danielbrookes]

Thanks for all the replies, lots of useful info. Looks like I was right about the 8.8 - didnt know about the difference between bolts and set screws, I do now

 

Does anyone have any idea on Quantaties and types, e.g but 50 x 50mm M8?

 

At the moment I have no idea what quantity and length of bolts I need which is frustrating, I dont want to waste money on ones I wont use.

 

Thanks

I can't comment on quantities as I haven't finished yet, I'm mostly just buying them as I go though really

[MarkBzero]

All I can say is don't under estimate how many nuts, bolts, washers (all types) and rivets you will use during the build. I used eBay http://stores.ebay.co.uk/About-Town-Bolts very good service and quick delivery.

[danielbrookes]

Thanks everyone, I think I'll buy a couple of mixed packs and go from there.

Any left over will be useful for your next kit......
