Geoff, The bolt (might need a button head for clearance if drive side) and nut properly tightened will hold rack to braze-on with clamping force. It won't budge over bumps or cause any problems. Lots of older bikes have unthreaded braze-ons meant to be used exactly like this.
I'd go this route in the OP's place. I do this on perfectly fine rack mounts anyway. Belt and suspenders approach.
