Makers marks on OEM bolts

Ive noticed a wide range of makers marks on OEM bolts and thought Id start a thread on the topic. You dont see these on new hardware. Here are just a couple for starters. Feel free to add others and Ill post more on occasion.

Re: Makers marks on OEM bolts

"Ferndale" fasteners and "Lang" fasteners were a couple that I remember.

Ferndale was designated with an "F", I don't recall if Lang's had anything on them at all.

They were used for front fender to rad support attachment, among other locations.

Re: Makers marks on OEM bolts

Here's another one - inner fender to outer fender from a 1970 C10.

So far I think they are NLA unless you find old stock.

They (the U-Nuts) appear to me made from a single stamping; and it must have been a big press to flow the steel around in the die so much; unless they are stamped red hot but that sounds difficult too.

The only maker's mark is the diamond shaped logo.

Re: Makers marks on OEM bolts

When I first looked at the title I was thinking why would you put whiskey on bolts...


I do try to reuse the originals if possible.

Re: Makers marks on OEM bolts

Was hoping you would chime in Keith. If Ferndale used an Art Deco looking F its my favorite. The anchor logo is a close second.

After the clear zinc replate the finish is brilliant and hard to capture - awesome looking bolts when in hand. These examples here have captured cutting washers and were used to afffix harness ground wires to the rad support and the clamp for the battery tray.

Re: Makers marks on OEM bolts

Again hard to capture the finish - these have cutting washers and are used to affix the reverse and tail light lenses with some dum dum along the threads.

Re: Makers marks on OEM bolts

I'll follow this thread. I too am fanatical about fasteners and details.

I once bought a 71 Monte Carlo just for the horn relay. It was a one year only relay, and I needed it for a Corvette I was restoring.

Re: Makers marks on OEM bolts

Interesting topic. This is a significant portion of NCRS Corvette judging where the head marks varied over at least the solid axle years. I have experienced it firsthand. I also reused most of my originals on my truck.

Larry I used a local shop when I was living in Albuquerque, Kaehr Plating (http://www.kaehr.com) IronCanine has used them as well.

Other members have used Arrow Plating in Ft Worth (http://www.arrowplating.com).

I’ve replated all sorts of stuff and have been really pleased.

Re: Makers marks on OEM bolts

Yesterday I installed a cool little 3/8 bolt for the distributor hold-down. It's the only one like it off the truck. Recessed head flange bolt, 3/8-16 x 9/16", stamped "E". Not tapered.

Few weeks ago I installed a bolt marked with a triangle for an A/C support bracket. Kind of cool, because the bracket is stamped with a triangle as well, almost as if it were a kit.
