CS BPV - Replacement Stainless Screws?

[iammike]

So I've had the CS BPV for awhile now but one thing is bothering me. See attached picture.

Where can you get stainless versions of these screws? If that's not easy to get ahold of, I'm going to try and find something stainless with the same thread pitch and such cause the rust is driving me crazy.

[JgamB]

Me too - such an awesome part, but those little buggers are eyesores and might be an issue by the time I take it apart for lubrication.

Check Ace Hardware, they have a huge selection of stainless screws, bolts, pan head, socket, etc . They also have a chrome section as well. Its where I go to get that kind of stuff since Lowes and Home Depot suck balls as far as selection goes.

[Spec]

If it is metric, good luck finding them in stainless at a local home improvement. They're very limited.

Do yourself a favor, take one out and find the thread pitch and diameter, also the length. If they don't have them there, just go ahead and order them online. Doing this would help you from finding out you can't find it, and looking all over creation for it.

The chrome plated ones may Crack when tightening and start to lift off after awhile putting you in the same boat .

There is an are hardware clear on the other side of town from me with a big metric selection. I don't know if ace is nationwide, though.

[Cirruslydakota]

I was missing the socket head screws that hold the MAF sensor in on my MS intake, went to ace out of frustration from the other places and they had them in the correct size and pitch. I was blown away so I started looking at their selection and they had a hell of a lot of specialty metric sizes.

Same happened to me with some other stuff, except the Ace that has it is 35 miles away or so. If I'm not in a pinch, I won't drove 70 miles for 2$ of bolts lol. Just order them shits online. That's why I suggested to find out ahead of time what the dimensions of the bolt /screw

[iammike]

I'll try and find some time this weekend to pull one and find out the details.

Happened with my wheels on the CX-7. Fastener shop ordered em. Just took one in.

Actually, I really don't have the time for this this weekend. @CorkSport; help us out here, I'm sure you have the screw specs you could share with us!

Are you expecting the vendor to be working Memorial Day weekend? If so, you are gonna have a bad time.

lol, true enough. Guess this is just going to have to wait then.

[Cirruslydakota]

Don't go to Fastenal, you'll be importing shit from other countries and waiting 2 weeks to find out they never ordered it anyway. Ask me how I know.

[Raider]

This place rocks. Not sure if they ship. http://www.flafasteners.com/?nomobile=1

Big factors will be not just thread size, but the head.

Other option is to remove Allen head screws, soapy water scrub, then dry. Paint em and reinstall. Use painters tape on the Allen wrench.

[Amnesiac]

I took mine out and measured. It's 4mm x .70 and 8mm long. Having said that I have the older version of the BPV where the screws are inset into the head of the valve so it may be different than what you have in your picture.

Here's an amazon link to a stainless replacement.

[punkk77]

Yes, the 4mm x 0.7 is right. I had to get some new ones because the originals seemed a bit short and wouldnt bite. Found some at HD, just not in stainless. I did have to grind the heads down just a bit, as the replacements had slightly bigger head diameter.

@iammike;

PM me your address

I am looking for these bolts as well, mine rusted like 2 weeks in to own the BPV. It works fine don't get me wrong but it looks like crap. Kind of upsetting... Still love you CS

Considering buying this BPV and just going to order them at the same time if these are correct. Don't need no rusty screw heads. I know Synapse claims the non-stainless ones "help maintain torque" by galvanic reaction, but it's kind of a bunch of crap to say "we depend on corrosion and rusting to keep our fasteners in place".

Just a heads up: I ordered them from that link and the estimated delivery date is the end of June to the start of July. So if you want them quickly for some reason I'd go a different route

Sweet Jebus! Thanks.

I notice McMaster has a "Magni-coated" screw that claims 1000 times more corrosion resistant than zinc. McMaster-Carr ...I wonder what color they are. I've heard of a coating that sounds like that and it's still sort of silvery, but gray.

McMaster also has two part numbers for SS:
McMaster-Carr
McMaster-Carr

Hmm, turns out of the three Fastenal part numbers, one of them is in stock at my local store(s) anyway.

[SuckSqueezBangBlow]

Thanks for the post above, gunna give them a call and ask for some samples.

[JgamB]

Over a month earlier than the projected arrival date - I'll give em a test fit in a little bit.

[JgamB]

Yep, same length, allen head, and thread pitch. These are the bolts from Amazon that @Amnesiac; linked.



This looks better



And this looks a helluva lot better. Hopefully it will stay that way.

[iammike]

Good deal. Looks great!

[JgamB]

Yes indeed. I think @CorkSport; should contemplate replacing the hardware on their inventory - this cost me $2.25 per unit and takes ~5 minutes. I have two more local friends that just ordered CS BPVs mostly because I told them this thing is fast and trouble free. It might seem like a minor issue, but the "before" picture illustrates pretty well the yuck factor of a little rust.

The big question now is...are the screws shipped from China really stainless steel. Only time will tell.

The third one I linked from McMaster, in a known variety of SS (18-8; probably the same as your silverware), are 6 cents each or 36 cents per unit. Even if shipping fills it out some, it's gotta be a fairly negligible part cost increase.

I bet their original thinking is that it looks cooler with black fasteners. Maybe it does at first. But to me it looks just as good with the silver ones. Once you screw the BPV down with silver screws, and since the fitting on the top is silver, there's no reason more silver doesn't look fine.

Gun bluing works on the non-stainless... but made me go look at my synapse, not stainless and not rusted...

[aackthpt]

No but they are silvery (zinc-plated) like most everything else in your engine bay, not the regular black oxide (I presume) cap screws like CS is using.

[acousticdefbot]

whatever the reasoning for these pigmented screws, whether for looks or with some scientific rationale in mind, i just want screws that won't rust. this stainless option is a great substitute.

[Sinister_Speed3]

I am going to order some of the screws since mine are rusted out aswell, do they need to be torqued ?

Thanks

I did my best to replicate what I broke them at with the allen wrench. I'd call it snug plus a 1/4 turn. Corksport will probably have the particulars if you want to be 100% accurate.

1/4 turn is a lot past snug. Maybe an 1/8 at most.
