brake plate mounting bolts

Does anyone happen to know the proper size/thread for the 5 bolts that hold loaded brake backing plate on?

Somewhere in Idaho, 50 miles from Airstream, new brakes, forgot to check bolt size for replacement. Hoping someone knows and can save me another 100 mile round trip hardware run.

Oh, and are stainless steel bolts and lock nuts strong & appropriate for brakes?

Thanks

Use the grade 5 or 8 bolts. Grade 5 have three bumps on the top of the heads and grade 8 have 6 bumps.

Thanks!
The Dexter specs gave the needed size. Big help.

I installed new Grade 5, 3/8-24 x 1 1/4", bolts with Grade 5 nuts and new lock washers, new loaded backing plates, bearings, races and seals.

It had studs pressed into the old backing plates instead of bolts (from 1964?).

Machine shop dude measured the drums at "exactly 12 inches", saying "These have never been turned and don't really need it now....had him clean them up just the same. We decided new thinner "China metal" backing plates were probably better off with bolts than pressed studs.

Headed for Alberta Rockies! Now I have real BRAKES!

Thanks for the help.
