Can anyone recommend a good place to buy replacement automotive nuts and bolts? I am trying my best to refurb running gear before I start my build. Most parts are going to be powder coated but I wanted new steel bolts to go with it rather than the old battered ones I have just removed.
Namrick do lots of fixings.
A-Series spares sell reasonably priced imperial socket head bolts.
I bought plated bulk packs from Screwfix - turned out quite good value doing it like that - I won't need to buy any more for a while !!
Ive bought from Orbital fasteners a few times., no problems at all
+1 for Orbital if it is not on their website phone them
Yep, Orbital here as well. Always been very pleased.
Mart.
Namrick is a good very reliable supplier but these days you will loads of suppliers on ebay who undercut on price.
If you search around locally you should be able to find a nut and bolt specialist...
I got to know the guys in mine quite well as I would go in with the weirdest bolts and want replacements :-D
Thanks guys. Orbital seem to do just about everything so will probably use them although screwfix would have been preferred as they are right next
door.
Given what they are being used for and I can't afford for them to fail what spec should I be looking for when ordering? Obviously the size is a
given but is there a difference between materials and/or coatings that should be taken into account.
Don't use stainless for for anything that could kill you if it fails.
I don't use less than 8.8. Never buy anything from B&Q as they are made of cheese.
There are opinions that you shouldn't use stronger than 8.8 on suspension as they go with a snap rather than bending first if you hit a curb.
There is a truly huge discussion on here about bolt strengths. Everyone seems to have their own opinion. So i suggest you get searching and do some reading. I used 8.8 grade bolts bought from Namrick for strength critical applications and screwfix specials for non-critical stuff. I used stainless where I could but deffo not for critical parts.

Stainless is more brittle than normal steel bolts, and rated differently regardless of the shape of the bolt. Normal capheads are often, but not always, 12.9 grade.
This is a comment that I see battered around the internet a lot but I've not managed to find any evidence for it. I know stainless suffers from work and heat/age hardening which can make the likes of stainless manifolds crack before a mild steel one would, but I'm not convinced that follows through to stainless fasteners. Just digging through a few references on the topic to see, but I suspect most people aren't even aware that Stainless screws come in both material grades (A2, A4 etc, loads of them) AND strength grades 50, 70, 80, 110 etc in a similar vein to 8.8s, 10.9s etc in mild bolts/screws. I haven't found comparable elongation to failure measurements from a reliable source yet, so can't really draw a conclusion, I just think it's not that simple.
