Brian,
Oh, they sure do look right. The seller has them listed as 5/16 but I have asked him to check. THANK YOU.
You may be interested to know that my old ones (one) was sheared during a UPS shipment. I have drilled through the two pieces of th4e broken bolt and tapped/fitted a 10/24th brass machine-screw insert. Set it with epoxy then ground the end flush. From the front one cannot tell that a repair was done...but I sure would like fresh ones.

Happy to help. Ever hear of an easy-out - though your way works also. If these sheared in shipping, what does the rest of the amp look like?
Actually, considering the poor packing, it survived better than one would expect. In addition to the broken faceplate bolt, one cage screw was distorted and ruined, but the cage itself was OK. The worst mess was with the bias meter. The weight of that meter was sufficient to break it loose, and some unknown portion of the journey went along with the meter bouncing loosely on the chassis. As you may have guessed, the sheet metal case of the meter assembly is distorted, with evidence of bulging where the heavy magnet inside made contact. It is not as bad as you may think and not noticable unless one makes a careful inspection. Of course this is not visible fron the outside, with tube cage in place. When the meter broke loose, it busted the little ring clamp, which prevents the assembly from rotating in its housing. It also sheared the plated, brass thumbscrew. In this case, I ground down the remaining shaft, flush with the brass thumb portion of the fastener. It was then easy enough to drill and tap for 6/32 and epoxy in a new brass threaded section, previously cut to original lenght. The busted clamp-ring was more challenging. The repair was accomplished by first bead-blasting the nickel plate from the brass ring. A matching brass doubler plate was then silver soldered on. Finally the ring clamp was replated in nickel. All looks just fine now, but took far more effort than a decent packing job would have done, in the first instance.

No Brian,
I must not have been clear in what I posted. I had no difficulty
removint the broken off portion of the bolt from the threads on the transformer. The drilling/tapping,fitting a brass insert, were done to restore the broken bolt, not to remove it.
