Polished stainless complete bolt kits for big twins.

[Smarty]

Does anyone know if anyone but Diamond Engineering out of Florida makes the polished stainless replacement bolt kits for the big twin motors? Diamond is almost $350

try alloyboltz.com, always good prices. Mike

 try:
allensfateners.com    ...for ARP or either chrome, or stainless bolts.
He charges the same $6.95 flat rate shipping for one bolt...or a hundred bolts.

Thanks guys. I knew some of you would know some others than Diamond Engineering. They are proud of their bolts for sure. I just checked out Alloy and much better pricing. Would you go with show polish stainless or the show polish grade 8 stainless on the primary, cam, covers, etc.

 I don't care for stainless bolts into aluminum...myself.

If you ever plan on taking it back apart, spring for the grade 8.

That's exactly what I'm ordering. Doing it right the first time!

Why is that Ray? If torque wrenches are used, should be no problem of pulling the threads out I would think.

[No Cents]

 stainless bolts that have been bolted into aluminum don't play well together over time...even if properly torqued.
The different properties of the two metal alloys is what I'm referring to.

Funny but I don't have any issues with them. like better than grade 8 Allen.
What becomes an issue is 304 into 304 without any lubricant. Can lock up tight.

[No Cents]

 I've just seen too many stainless bolts pull the threads out of aluminum when removing them. I ended up having to Heli-coil the bolt holes on many different instances.
Maybe it was just bad luck...and I wish it on no one...just stating what I've seen.

[JohnCA58]

I have stainless ARP 12 pt. throughout my engine and transmission, always used a stainless dedicated lubricant and never had any issues.

Have always order from Alloyboltz.  Husband and wife team operating out of their garage.

[SOCS]

+1 for Alloyboltz. Been buying from them for 13 years with no issues

[Admiral Akbar]

I'd suspect that the bolts were torqued too high. Especially if using ARP bolts. Finish is slicker than grade 8.  With a lubricant, its even worse. I use 304, torqued to 304 specs and a little blue and no issues to date.

I learned from the local shop that the proper loctite for the job will not only keep the bolt from coming loose but I have never had a reaction between the bolt and the aluminium or had to helicoil a hole.

Not to take this off topic but every bolt gets a tq wrench.

   Drop of blue on the threads and min torque in a PROPER pattern never  had a problem been doing it that way since the 70s when Loctite was first shown to me. If bolts are not tightened in steps and in a proper pattern you will create problems with over tightened bolts.  Bob

exactly, Alloyboltz includes paperwork that notes the lower torque spec

Thanks for all the comments. I'm ordering on Monday from Allow.

Alloy Boltz advises use of lock tite to prevent dissimilar metal corrosion. I have been using them for 10 years without any issue. I am too cheap to buy the full polish and the standard ones are a "light" polish look good and do not corrode like the stockers in 2 years. Mike

[Xanadu]

to prevent galling be sure to use some kind of lubricant.  once the bolt galls its cold welds itself and you cant take it apart.

I wanted to replace all the zinc plated fasteners on my motor with nice chromed ones... decided not to do that based on what I read at the beginning of my service manual.  Another thing I have found with the chrome plated fasteners is you can see orange in the allen sockets and around the bolt as the underlying steel rusts.  the stock HD bolts which are zinc plated hold up much better to corrosion  and I dont have to use a q-tip with polish on it to clean out the inside of the allen heads.

I had to deal with this all the time maintaining/installing equipment on my boat. Obviously more apparent in a marine environment, but galvanic corrosion can/will happen when dissimilar metals come in contact with each other.

Limit the contact (isolate the metals), or exist in a less corrosive environment and the galvanic corrosion will be mitigated.

I've always found the stock Zinc Plated and S-100 don't play well together... unless you use something close to the amount of water in Lake Eire to rinse the S-100 off.

Good stuff.. This chart puts the 2 metals closer on the Galvanic Chart..

http://www.engineersedge.com/galvanic_capatability.htm

While SS is more anodic than simple steel, both can corrode and stick in aluminum, especially when there is a electrolyte involved..

You can use the show polished stainless from alloy boltz, that's what I did.  They look awesome & they send a small vial of Z-42 medium strength thread locker with the order & say make sure to use it.

I've put complete kits from Alloy Boltz on the past 3 bikes I've owned and never had a problem with one of them.  Also haven't had to look at those nasty stock fasteners either.  I've had the show polished and the regular ones.  IMO, the show polish are a waste except for in places that are right in your face like switch covers.  The difference between the stock bolts and the regular polished is stunning.

[akjeff]

I've had good luck with polished Grade 8 from AlloyBoltz. Nice folks to deal with, and nice product. I just use Blue Loctite(or anti seize if safety wiring), and torque to the lower spec they suggest with the instructions.

Rags, what did you see happen with the stock zinc plated stamped HD allen head bolts and the S-100?

I use S-100 engine brightener after each bike wash and have never noticed any detremental effects on the stock Allen head HD bolts.

Let me know what you saw, I would like to look for that.

[Smarty]

My order from Alloy Boltz shipped out today. Complete kit and the caliper kit as well.

I've used S100 since the mid 80's and haven't seen any problem.  You don't want to use on a warm engine or let sit in the sun.  Several years back Honda and Suzuki cleaner were S100,  don't know if they still are.

I seriously doubt the S100 engine brightener would ever be a problem for corrosion. The total cycle cleaner, possibly. I looked for an MSDS for S100 but could not find one, but my bet is the brightener is mostly silicone and propellant.

I get the convenience of pre-packaged 'kits', but for the OP, have you consider simply looking up the various bolt sizes none of the online harley parts manuals and buying the fasteners from someplace like Summit?

I have been doing this for years. The bolts typically come with washers and are sold in packs of five. The five to a pack will typically result in having a bolt or two left over, which is not a bad thing. After a few years of doing it this way I have a pretty good selection on hand of 12pt ARP hardware. Very handy for to have unhand for new projects or lost/missing bolts.

I source them from Summit with is probably lower than most other resellers.

  Ed...save yourself some money next time and get your ARP bolts and nuts from:
allensfasteners.com

  I just looked at your summit page and then went to allensfasteners to compare prices...much cheaper than summit.
If you know the size and lengths of the bolts you need...it would definitely be cheaper than buying a kit. He sells stainless, and black oxide ARP bolts, in 12 point and hex head. He also sells chrome bolts in SAE and metric.
Just trying to help.

[turboprop]

I did a cost comparison last year with Allens Fasteners, maybe it was just the odd combination of sizes, but it was less expensive going to Summit. As I recall Allen charged extra for the washers, which I needed.

[No Cents]

 even buying washers separate...it's still cheaper than summit.

Summit

allens fasteners
[attach=1]
[attachimg=3]
[attachimg=4]

  and here is the kicker...Summit charged $9.95 for shipping for the 10 bolts pictured...while Allen's fasteners charges $6.95 per order...if you buy 1 bolt or 100...the shipping is still $6.95.

[DoubleZ]

So if you buy the bolts individually how do you know what the new torque specs should be?   I've replaced a few bolts on my bike with the black ARP stuff but didn't realize the torque specs should be different.

We use this product from Swagelok on all our stainless hardware in the power plant i work at . Works real nice and ive never had a problem with galling using it .

I am a big fan of Alloyboltz. I've been using them for years and I like that the wife kept the business going. I don't get the show polished, the standard 12 point stainless looks great and holds up well.

At first I used never seize but I would occasionally have some fasteners loosen and get a leak?

I used blue Loctite for a bit but was concerned about dissimilar metals and galling?

I believe I read it here but I started using Aviation gasket sealant. Just a dab to coat the threads. Never had a bolt loosen and I've always been able to remove any bolt I wanted to?
