8.8 steel or A2 stainless ?
8.8 , I wouldn't use stainless
Cheers Mel
As said definitely not stainless. I have used 8.8 and 12.9 on steering UJ's etc...

A2-70 SS are low tensile, standard bolts.
I have used A4-80 which are a higher strength stainless bolt.

Stainless goes brittle in reciprocating loads - you need high tensile. It's great if the load isn't under any vibrational loading.
I used 8.8 set screws at either end of the shocks on my MK Indy - didn't suffer any mishaps with this setup. From experience of a pro welder friend fabricating a stainless trailer I'd be apprehensive of using stainless bolts as I'd imaging they'd get damaged after a while.
AN bolts are the best to use imo
I would not be using set screws in suspension components. You want a shoulder where there are any stresses (badly worded)

A2-70 = 7.0 304 material.
A4- 80 = 8.0 316 material.

I must admit that until I Googled AN I didn't know what it stood for.
I'm impressed. Did they cost an arm and a leg ?

Not really, just a bit of pain to find them! All over USA but not much here.
Maybe once we vote out of the EU someone can import them from the US![]()
Trident Racing Supplies based at Silverstone have a massive range of AN hardware. They do mail order. Not that expensive either for life and limb items. Their catalogue is a must have ( also on line ).

My car has AN bolts for all the suspension stuff - the main reason I used them is so that I could get the correct lengths of plain shaft and threaded
bit. The range of sizes is so broad that I was able to get the thread in just the right place, at the point where it comes out of the bracket.
They're also made of high-grade steel.
Unfortunately (for me) although I bought them from what I thought was a UK supplier, they were just an agency for a USA company, so I got severely
stung for import duty and courier handling charges - nearly doubled the price.
LAS Aero, Trident, Autosport Bearing Supplies, and a number of others have AN bolts in stock.
I've been using 8mm ground shoulder bots from Cromwell(and others) for the purpose for near 30 years.
