I've purchased some NOS mechanical brake wedge studs and they don't have
any cotter pin holes in their ends. These studs are incredibly hard and I haven't
been able to drill them even with my cobalt bits. Any suggestions as to how I can penetrate these babies?

Use a split washer ,or cut a slot with 1/16 cut of wheel ,then run a dye on back wards ,braze up 3/4 s of the slot ,then run the diy nut off .Or heat the end red hot then dump it in Ash to cool it .that will soften it .Ted

Is this what you're referring to? > https://www.bobdrake.com/FordItem.aspx?Item=BB-2466

The bolt on the bottom of the brake backing plates. The brake wedge fits over this bolt. In 35 it was a bolt affixed with a nut and cotter pin. In 36 it changed to being a rivet. All the 48-2053 Front, I have seen have the cotter pin hole. 48-2223 on the rear wheels also has the cotter pin hole. My GUESS is you have a probably much later replacement that is supposed to use a special lock nut.

In my 28-37 parts book (printed july1945) it shows castle nut with cotter in 35, try and look in the "green book"---postwar many castle nuts werte replaced with marsden nuts---a self locking nut, this reduced costs by a lockwasher, cotter pin, the production operation of drilling, chamfering the cotter pin hole and the labor to install them,

I looked in the green book and they show 33846-S8 for the nut which
is a regular hex nut.

Thanks to everyone for your comments. As a matter of interest I'll try Ted's
suggestion about heating the end which I'm sure will adversely affect the
hardness.
