G,day,
On a steel roller, came with a 3/8 unc thread.
Are they able to be drilled and tapped for a 7/16 or 1/2" unf or are they too hard?
Thanks very much!
Paul

Gday Paul
If the opposite end of the cam isn't used, you could test a drill/tap. This will confirm, on your specific core, whether it's feasable.
Regards
Paul

Probably drill it with a, "hard-bit", like a Cobalt type.
I was at SEMA years and years ago and a guy was hawking them. He let me drill through the middle of a big Nicholson bastard cut file! Then a rear end leaf spring!

The center of the cam won't be real hard and it usually is pretty easy to drill and tap to 7/16-20
