Is it ok if i use bolts to attach my crossover steering arm, instead of using studs?
Will it be as strong as the studs are?
I should use Grade8 bolts right?
thanks later,

studs aren't grade 8 so the bolts shouldn't be, pretty sure they are grade12.

With that said I have bolts and not studs since nobody makes em for the 1/2" spacer I have under my arms <IMG SRC="smilies/frown.gif" border="0">

I'd say just keep an eye on em and don't forget the cone washers <IMG SRC="smilies/smile.gif" border="0">

Metric studs/bolts come in a 8.8 which is equivalent to a Grade 8 bolt. Standard grade 8 bolts can be identified with the six (6) markings on top of the bolt head. An 8.8 will have that number stamped. As for grade 12, I am not sure I have ever seen such a thing. Most bolts/studs conform to standard ASTM ratings.

I went with 8.8 bolts when i built my custom arms, and no problem, but my rig also does not steer off the pass arm either...

I'll bet he's talking about the SAE studs on his D44 steering arms, so forget about the metric stuff. <IMG SRC="smilies/wink.gif" border="0">

Studs are the better way to go, but some people use bolts instead. Search the general section for pros/cons. Its been discussed several times before.

I happened to have the book on my desk, An 8.8 grade metric is equivalent to a grade 5 standard. A 10.9 metric is roughly equivalent to a grade 8 standard. Studs are marked as follows: a diamond or square stamped in the end is a class 10.9, an x or cross is a 9.8, and a circle is an 8.8
Hope this helps <IMG SRC="smilies/smile.gif" border="0">

Why studs?

As I understand it (and I could be wrong), when one torques a bolt, an extra torsional stress is placed on the whole shaft of the fastener. When you tighten a nut on a stud, much less tosional load is placed on the shaft as you are simply spinning the nut down onto the shaft. Fasteners are designed to be stressed lengthwise in order to achieve a certain clamping strength. When they are also stressed torsionally, it makes them weaker.

I read somewhere that bolts are the penny pinchers choice, studs are the engineers choice.

The main difference is not the stud vs. the bolt, but rather the imporatant thing is the CONE WASHER.

The cone washer is what makes the studs superior - their ability to be tightened and STAY tight are far superior to bolts.

Their conical shape also removes all slop between the pieces - making for a much better fit.

Remember - the stods or bolts are not there to actually hold anything on, they are just there to keep the frictional forces applied between the arm and knuckle surface - that friction is what is seeing the loads.

That being the case, anything you can do to keep the pieces fastened to gether TIGHT - you are better off.

So Brandon - you telling me you can't find studs that are long enough? Check with one of the companies that sells the Chevy driver's side lifted steering blocks - they use longer studs <IMG SRC="smilies/smile.gif" border="0">

I have to use bolts cause i need to make a 3/4" spacer for the steering arm and studs will be too short.
Are you collectin part for your SAS yet? If ya need me to check my local salvage yards for any parts just lemme know, i usually get pretty good deals! <IMG SRC="smilies/wink.gif" border="0">

Good idea, i might have to check into that...i already have the bolts that i need, and ill just use em as long as they will be just as good as the studs. What would you do, just use the bolts i already have or replace the bolts with studs?
thanks <IMG SRC="smilies/wink.gif" border="0">

I think these guys started out w/ flat arms and realized they needed more (spring?) clearance... so bought spacers.

Flat arms seem fine for me though. <IMG SRC="smilies/smile.gif" border="0">

Hey Skank, is that a Roggy bent arm? Does it have a twist in it to make the end level instead of angled w/ the knuckle? I was thinking of having him put a twist in mine...

It's a Roggy arm. There's a 1.5 degree twist, according to my Blue Point angle finder. I imagine it's more an artifact of the press breaking than anything intentional. If you find out he can put a twist in them let me know! BTW, are you having your flat arms twisted? My flat arms are much more substantial than the stepped arms and would take a lot more grunt to get a twist into!

What are the measurements of the studs you need??? Dia, length and thread pitch. They havew to make some, they make studs to replace bolts for just about parts on a racing engine. <IMG SRC="smilies/usa.gif" border="0"> <IMG SRC="smilies/usa.gif" border="0"> <IMG SRC="smilies/usa.gif" border="0">
