Need help with proper fastener finishes

[Greg L.]

Could someone please tell me the proper finish for these various fasteners for my 69 BB non AC car.

:Bolts that hold the headlight frame to header bar(3)and the front nose piece(2).
:Bolts that hold the rad support to the inner fenders.
:Bolts that hold the hood hinges to the inner fender and to the hood as well.
:Bolts that hold the hood latches to the hood.
:Bolts that hold the hood release cable clips to the hood.
:Bolts that hold the hood support to the inner fender and to the hood also.
:Screws that hold the fan blower motor assy to the housing.
:Nuts that hold the fan blower motor housing to the firewall.

I hope this isn't asking too much but I've looked through the TIM&JG over and over and can't find this info. Once again, thanks for your help.

Re: Need help with proper fastener finishes

Paragon has a bolt reference chart that may be of some help. You may want to write them for one. Also check some of the resto books in the market... Tripoli's book has some info in it also...

Good luck and good hunting

Re: Need help with proper fastener finishes

Thanks Steve. I'll look into Paragon but I already have various books and so forth to do my research with. The TIM&JG for 68-69 I'll have to say is by far the best of the bunch but not all manuals/guides can be complete.
With this said, I thought it would just be quicker and more accurate to throw the questions out here in hopes that someone with a Top Flight 69 or someone who judges this year would respond with what they feel would be an acceptable fastener finish for a future Top Flight candidate.

Re: Cad or Zink plate everything

If you do this there will be no rust etc. You can always paint the plated items.

Greg, the following information is correct for late 70...I'm about 80% percent sure it will be the same for your car. Keep in mind that different shades of phosphate will be observed on different cars, so when I say BLP or DGP, it could be either.

:Bolts, headlight frame to header bar(3)and front nose piece(2). BLP
:Bolts, rad support to inner fenders. BLP
:Bolts, hood hinges to inner fender and to hood. BLP
:Bolts, hood latches to the hood. DGP
:Bolts, hood release cable clips to the hood. Zinc (1)
:Bolts, hood support to inner fender and hood. BLP(3), Zinc(1)
:Screws, fan blower motor assy to housing. BLO(?)
:Nuts, fan blower motor housing to firewall. BLP

BLO=Black Oxide
BLP=Black Phosphate
DGP=Dark Gray Phosphate

Nice job Chuck.
I am compelled to point out that the hood and hinges (not hood support) were in place when the black-out operation took place, and thus the fasteners for the hinges received a coat of black-out paint. There is much more to be said about the black-out operation, but it has all been said already on this board and there is nothing to be gained by highjacking the thread.

Terry,

Re: Need help with proper fastener finishes

I agree. However, that IS essential knowledge and worth mentioning. I only responded to the question(s) he asked, and that is probably not the best teaching method.

I was uncomfortable about the (1)zinc screw for the hood support at the fender ledge. (Is it possibly natural? I choose zinc.) Since that screw and the flat steel reinforcing plate under it are in place during painting, the final finish will be body color (poorly done...didn't see any primer).

Chuck,

"I was uncomfortable about the (1)zinc screw for the hood support at the fender ledge. (Is it possibly natural? I choose zinc.) Since that screw and the flat steel reinforcing plate under it are in place during painting, the final finish will be body color (poorly done...didn't see any primer)."

I believe they are zinc or cadmium (silver color plate) - both the screw and square washer. Neither was in place during painting, so they should not be body color.

The hinges were in place during paint, as Patrick's photo so nicely shows, but not the other hood hardware.

nice picture - worth more than 1000 words *NM*

Re: fastener finishes

Terry, thanks for saving me some deduct points.

That screw and reinforcing "washer" on mine were body color, but the overspray must have been from the repaint. That explains why there was no primer, and the color overspray was adhering poorly.

I could have sworn the reinforcing washer was natural...like, for example, the shims under the wiper door mechanism. The screw looked like it could have been either zinc or natural, but zinc would wear pretty well in that location...I thought I was "over-restoring" it to zinc. But, if it wasn't painted, it was almost certainly zinc.

Re: fastener finishes

Thanks guys. I really appreciate the time you all spend answering some of my silly questions, and with a picture to boot! Thanks Chuck for your detailed list, that's just what I was looking for. I always wondered how this body paint/blackout combo in the hinge area looked and now I know.

As I go through my "little" project here and gain knowledge, I am adding it all to my TIM&JG in hopes that I'll have a complete list of proper fastener finishes when I am all done. Thanks again.

Re: fastener finishes

Greg,

It sure helps to have a Bowtie 72 in my garage. It answers a LOT of questions for me. Thankfully I have taken dozens of pictures of many items, so when a question like this comes up all I have to do is check my hard drive for the right picture and post it for all to see.

Re: Need help with proper fastener finishes

Two were missed:

:Screws that hold the fan blower motor assy to the housing. Guessing on this one -- Black, probably oxide
:Nuts that hold the fan blower motor housing to the firewall. -- Black phosphate
