ok, so i need some 3/8 coarse grade 5 or better bolts with a 1 or 1.25" shank with a flanged head which has a shoulder dia. of no more than 1/2". no one in portland seems to carry this type of bolt, which happens to be what is required for my pressure plate on my rig. the instructions which came w/ the pressure plate say i can't use a washer and a bolt - it must be a flanged head. why is this? any tips on where i can pick up the proper bolts?
 
there's a fastenall where I live, they have EVERYTHING, but you have to buy in bulk.

that's probably not much help though :doah: I'm sure somebody probably has one laying around they can mail you.
 
Since you live in a major city, if you look in the phone book, you should be able to find an "Industrial Hardware" store (not a regular hardware store like Ace or Home Depot). Industrial Hardware stores are mostly in the business of supplying hardware to local businesses because their needs are more specialized than any Home Depot can fulfill.
 
does anyone know why it requires a flanged head bolt instead of a bolt and washer? it would make it way easier on me if they didn't require it to be a flanged head bolt.

I thought that too of the one big industrial fastener store here in OKC, but they don't have 7/8-18 left or right threaded nuts. I thought they would. They did have everything else I've ever seen or heard of.
 
My pressure plate uses bolts and lock washers for whatever that is worth...

Try the stealership maybe.

Tacoma screw.. they are on columbia blvd, just down the rd from my shop.
Most parts stores should have clutch bolts, did ya try Baxters?

x2.

awesome place to check out. I've never asked them for something and found out they didn't have it. Lots of stainless stuff too. mmmmmmm... stainless...

i tried baxters, i love that place, but they didn't have flanged heads. i think if i can't locate them easily tomorrow, i'll just do like rene. thanks guys.
 
ARP pressure plate bolt kit, # 130-2201.
Gotta ask for the right stuff or ya confuse em.
 
"Good" parts stores have them..

"HELP" and "Dorman" both make pressure plate bolts--most parts stores here either stock them,or can get them in a day..I've used "regular" grade 8 bolts and washers that have a slight shoulder under the heads with no troubles on many of my own and others trucks (or re-used the stock bolts)...Allen head bolts might work good too..they are grade 10 if I remember correctly..just dont use any bolt with threads all the way to the head,they'll snap off too easy..

I love living close to junkyards when little 10 cent items like this frustrate the hell ouuta ya!--no better place to get the correct factory parts,and at cheep prices..:crazy:
 
I got mine at the driveline/clutch shop where I bought the clutch.
I would check with wherever you got the clutch (assuming that's possible)
 
well, the parts stores all had the arp stuff, but they've got a 9/16th head, plus the shoulder. oh well, i got the problem taken care of. ;)

The 18 pitch thread is the uncommon part. The two common pitches in 7/8" are 9 and 14 tpi.

Wait a minute, how are you going to have a shoulder diameter of less than 1/2" when the head of a 3/8 bolt is 9/16?
Anyway, here's something... http://www.madmyk.com/gallery/albums/Fire-Apparatus,-Red-or-Yellow/104_Bright_Green_LaFrance.jpg
I don't remember the pressure plate needing anything that special. Also, I was thinking that those were fine thread? You're talking about bolting the pressure plate to the flywheel right? I think I had just normal hex cap bolts with star washers on mine.

Edit: Nevermind, they are course. It's the crank that's fine.

yeah, i was really struck by that. i think maybe the pressure plate can go on multiple types of vehicles, and maybe some vehicles have a smaller thread diameter than 3/8 such that they wouldn't have this issue. i ended up using some which were 9/16 and called it good since that's super close to 1/2. :)
