C2 "High Hat" FI "S" Tube Screws

[Floyd #21606]

Does anyone have a picture of the "High Hat" FI "S" Tube Screws.
I don't have any screws that I could take a picture of. I may have a source for the "High Hat" screws if I can show them a picture of what I am looking for.

Thanks

64-65 "High Hat" FI "S" Tube Screws

If I can find this screw again, I'll rescan and show the indented top if needed.

Hi Michael,
Thank you very much for the picture, it sure helped. If you can find the screw
I would appreciate a copy of it too. I will let you know if the possible source has the screws, maybe we can help other members who may need these screws too.

Thanks again,
Floyd

I'll try to find it Floyd. The scan I posted was done a few years ago and I have no idea what box I put these. Could be in with the FI stuff I suppose.

The "high hat" screw isn't near as difficult to find as the 63/early 64 style. John Hinckley posted a while back and mentioned that 65/69 Corvair used these everywhere so they should be pretty common.

Also, there were several used on heater assy's for Corvette and, I believe, passenger car.

Re: 64-65 "High Hat" FI "S" Tube Screws

I still have some in my stash (which mysteriously found their way out of the Willow Run plant in 1965 in my pocket); all have a slightly indented head, some have two concentric rings with an "A" in the center, some just have an "A", and some have no headmark at all. All came out of the same bin on the line which was refilled by the stockchaser regularly, based only on the part number on a box; nobody cared about suppliers (and nearly all fasteners had multiple suppliers in those days) or headmarks - just the part number on the box. '65-'69 Corvairs had about 24 of them securing the metal retainer strips for the rubber engine-to-body seal that ran all the way around the engine compartment, and about the same number of them attached the long sheet metal underbody tunnel cover to the floor pan. Based on recent eBay bids, I may have found another IRA source [none for sale]

Michael & John,

I'm interested in the headmarkings and also the ends of the threads. I have several examples. All have the high hats and a recessed manufacturers logo. One is like Michael's picture with the exception of not being so pointed. It has a "O" for a headstamp. The other four have two anchors on the headstamp and have a self starting thread cut.

All of these were either natural finish or black phosphate. Cannot tell as it been about 40 years since they were new. Four of these (anchors) found their way into the cadium tank by mistake.

Regards,

JR

Anchor Head Screw

Here's one out of a real 65 FI car. Has two anchors in head.

Re: Anchor Head Screw

Thank you again for the pictures, I will send it along with the other picture.
Hopefully they will help find some of the screws.

Re: John, Miahael and JR

John, Michael and J.R.
I am trying to find 4 High Hat Screws, somehow I misplaced mine during my frame off restoration of my 65 fuelie. If you know of anyone who would like to sell me 4 I would really appreciate it. I don't have any Corvair/old car salvage yards around my area (that I am aware of). The salvage yards in my area have mostly car's that are 10 years or earlier.

Any information as where to purchase these screws is appreciated.

Regards,
Floyd

Re: C2 "High Hat" FI "S" Tube Screws

Anchor head screws were manufactured in the town I live in, I wonder how many of these screw and others made there way out in pockets? I'm very interested in the differance in 63-64 ones. My orignal early 64 FI car, has the type that Michael posted.

Re: 64-65 "High Hat" FI "S" Tube Screws

JR, about half of mine have the longitudinal "cut" through about the first four threads from the point, and half don't; all came out of the same operator's bin, so the "cut" may have been an "optional construction" on the drawing.

[Joe R.]

Re: 64-65 "High Hat" FI "S" Tube Screws

John, Michael & Others

The ones I have with the cut on the end of the threads are made by Anchor Screw and Bolt. There are two small anchors on the head with no other markings. These came from my 64 FI Roadster S/N 11,866.

The support had some predrilled holes but not as large as the screws. Every original I have ever seen had the bolts screwed in at an angle as it was nearly impossible to get any clearance to the S Tube. I've always wondered if the cut was specified to allow the screw to cut threads as it was installed into the small hole.

Inquiring minds want to know!

Re: 64-65 "High Hat" FI "S" Tube Screws

I really think either style may have been correct. Many times, there are "optional" part numbers on GM prints so any one of several different designs could have been used on the assy line, especially since the original AIM never listed ANY screws with the tall hex head for the FI air cleaner "S" tube.

If a few owners of untouched original 64 or 65 FI cars would look at the pointed end of these screws where they poke through the front of the core support, we may be able to document the fact that there is no "correct" screw. They may all be diferent.

JR... wonder what that low mileage red/black 64 conv near you has for screws? What about Jerry Devrees (splg) red/white untouched 64 conv? And what happened to the 20,000 mile white/red leather 65 FI coupe that Krughoff had? These are the types of cars needed to provide this kind of information.

Michael,

I will get some photos of the Red 1964 FI Roadster soon and we can feel sure that it's original. Wonder what ever happened to Jerry DeVries FI Roadster. IF Jerry is still alive he's kicking close to 80-85. Have a copy of his Dealer Invoice. That car cost $5267.50 and with the trade in of a 63 FI Roadster he paid $1092.00 difference. Sounds like a deal to me.

Regards,

JR
