Yep, I searched and there was no definitive answer. I have googled around and seen them anywhere from 10buck to almost 200...

Has anybody ever used these guys?

Seems a little pricey? But then again I have never bought a replacement set of case bolts...the Black ones look awesome as well

then at the opposite end of the spectrum, on ebay you have a 60 piece set for $9.99

I have a K8. I know there's been mention of many vendors sells replacement case bolt sets...please post up some reliable vendors, thanks guys. I'll continue to search and post findings here.

I got one of the ebay sets for my CB500 and it didn't have the correct number of the correct length bolts. Some were too short, some too long. I ended up re-using the screws on the bottom (read: hidden) parts of the side covers.

I got the following set off ebay for $36 (includes shipping). They were all sorted, bagged and labeled, correct lengths and appear to be high quality. So much better than the philips head, and won't rust. Note that the first link you provided are for aluminum alloy bolts- while lighter, you have to be more careful not to strip/break them.

I got mine from http://alloyboltz.com/catalog/product_info.php?cPath=316&products_id=2152 but i got them off ebay for cheaper. It worked well, they even had a kit for the carbs to.

Did almost my entire bike minus the small amount of specialy bolts including the complete engine for around 300. All marine grade stainless allens for the motor and marine grade bolts nuts and washers for the rest. I just went through the parts fische and ordered everything I could get. Took awhile but worth it. My bolts will never rust. Got everything from boltdepot.com. Highly recomended also great prices and fast shipping. Also get yoursef a tube of anti seize. Aluminum will gall when stainless bolts are used.

co425 - anything over 8mm (I think) is where JIS and whatever the other standard(s) is/are part ways. Bolt Depot doesn't sell JIS hardware that I'm aware of. How did you cover the larger stuff?

tlbranth · « **Reply #7 on:** May 12, 2010, 08:06:24 PM »

Oh and don't use aluminum antisieze, use copper.

anything that you have over 8mm if I remeber right are through bolts I.E. no captured threads so you have to use a nut. If I remember right those were only the frontmotor mount bolts. Even though the heads were bigger they still fit fine.

My understanding is that on a CB750, anything over 5mm is ISO and generally available. Only the 5s and less have the JIS identifying dot on them. If its larger than 5mm and has the JIS dot, its still the same thread as ISO. They were "unified" over 5mm.

The stainless vendors are aware of all these problems, just ask them, but I think over 5mm, its a non-issue.

One thing I found is there is definitely a quality issue from some suppliers, I found the ones I bought from the guy here on the website better then those I bought at the local hardware store, primarily in fit to its mating Allen wrench.

whats the difference between aluminum anti-seize and copper?

tlbranth · « **Reply #14 on:** August 02, 2010, 10:47:16 AM »

Apparently, you should use copper antisieze when fastening aluminum with stainless, if you use aluminum problems will occur.

Jim has a new website he gave when i got in touch ( www.screwsforcycles.wordpress.com ) but i think either one will work.

laser145 · « **Reply #16 on:** August 02, 2010, 10:56:31 AM »

Jim responded instantly when I emailed him from the old site, so I assume he's up and running with both.

hope you dont ride too much in the rain because basically, stainless and alu will create a voltaic cell which equals corrosion. the copper paste can do its best to try and protect but it has to fight the basic chemistry working against it. moisture will accelerate the process.

Good to know, but I never ride in the rain.

I ordered mine from http://www.stainlesscycle.com/

Good price on them also. I don't know how to judge quality, but they sure look really nice, and they all fit my 550 well although one bolt on the cam cover seemed a little short.

hard to avoid humidity and condensation. But, some antiseize on the threads and under the head will go a long way to making it livable.

How about copper plating the shanks and threads of the SS bolts and then polishing the heads? Sufficient protection from dissimilar metal electrolysis? Overkill?

I like that idea . Is there really any such thing as overkill ?

Good thread info, as usual.

PO chewed up a few of the Philips heads on my bike motor. Will need to be replaced sometime.
