Correct Fasteners and headmarkings

[68camaroz28]

Reply 163-reference head marking Marty has labeled #15.
Question or remark on screw #3846202 screw/bolt with supplier #15.
I checked numerous original #3846202 and could not find that #15 configuration.
Then I found a bag of new #3846202 screws that have that head marking.
Note the 15 on the picture (bag) below is what they cost, $15...
Just a concern #15 supplier type might not be be correct.
Can anyone confirm they have an original #3846202 wtih #15 head markings?

Chick - Thanks for this post. I've been searching for someone else who has the "LF" fastener. I am trying to find out when this particular fastener was used/introduced which also brings up another important question; I think most of us know the "Pinch-Point" & "Dog-Point" fasteners were introduced for use early into the First Gen. run. The question I had was; "When was the "Roll-Point" Machine -Thread bolt developed for use. I found this thread over at TC that I hope John doesn't mind me posting. John actually developed the "Roll-Point" fastener in conjunction with Anchor for use beginning with the '68 run. Maybe this can shed some light on wether or not the "LF" screw is a legit factory fastener.

Saw that "roll point" but until now did not know what it was called or have seen one in first gen camaro. Thanks Marty for the thread and later in that thread JohnZ mentioned "Production applications started with late '69 "B"-bodies built at Flint Assembly and spread from there in '70-'71 to other plants and other car lines."

I took out 2 bolts that were gold cad. and I can't remember where they go. Flange head 5/16" X 1". I do know they came from the bottom of the car.
They are unusual in that they have a square point to them and that they are the only gold bolts I remember taking off. Maybe someone else remembers seeing these.
Thanks

I too am interested to know if anyone has come across a similar fastener...distinct and unusual finish .

Can someone fill us in on the numbered head-marking? I have seen several. What does the number mean? Is it just one company who made these or were there several?

There were at least three suppliers for every fastener part number; I've never seen that headmark before, and have never seen a gold cad finish on an original fastener.

John thanks for the input, this head mark "23" is the similar to my door hinge bolts and shown on other cars also. I took an inventory of the bolts I took off the bottom of the car and I am missing 2 bolts that hold the rear upper shock mount. I guess these 2 gold bolts were replacements at some point.
However I do have another dilemma. The bolts I took off for the fuel & brake line clips are not all the same bolt. 1969 AIM shows #3958062 used in both locations but I have some normal hex and flange head bolts, see picture. Since my car is a Nov. 68 car I wonder if someone with an early car could check their bolts or if you have a 1968 AIM see if they list the same bolt number for fuel & brake lines. Bolts with hex head were used on the fuel clips & can be seen by scar marks on the clips.
Thanks for the help. George

George...the bolts you show for the brake and fuel line clips are the same size and shape  as the ones on my  07C 1968 Z28 (although the ones I have have several different bolt head markings) .  The number you cited above is not the same number as the one in the 1968 AIM.  I have both year model AIM's and I checked them for the numbers at each corresponding location and the part numbers are different.  The part number for the 1968 is 9420825.

[NoYenko]

Jerry, Thanks for your reply. This forum & members are great. The hex bolts #9420825 I have are marked "L", "E", and blank. They were also used on my brake bias valve.
There was propably a part number change on an early 69 AIM revision sheet that doesn't show on my copy.

George - here is that same bolt on mine (12A LA) "ER" headmark; 1/2" x 9/16" & 5/8" flange.

There were at least three suppliers for every fastener part number; I've never seen that headmark before, and have never seen a gold cad finish on an original fastener.

John - Here are a few more examples of numbered headmarks members have posted in this discussion..."36", "A-96", "O-98", "23" & "L8-86". Do you recall seeing any of these?

Thanks!

Not offhand, but that doesn't mean they aren't original; I haven't inspected many LA cars, and they're likely to have some unique fastener headmarks (sourced on the west coast).

John - your candor & tact never ceases to amaze. Thank you sir!!!

Guys, we need more examples from Van Nuys and Norwood. Please...there are no right or wrong answers. Just looking for examples & numbers...

Here is the latest update. PLEASE...if you notice any headmarks not consistant with what would have been used from the FACTORY please let us know. Again...green asterisks means factory and red means BS...
