Converting Quick Release Skewer to bolt-on axle

Is this true with all hubs using these kind of fittings or just the home converted ones?

I reread that when checking that I was linking the right thread, and now I'm in two minds about it. I've had no issues in terms of thread reliability with 6Nm on M6 screws in Shimano hollow axles, which puts the clamping force in much the same region as a good closed cam QR. While neither can be considered properly safe with disc brakes (only a through axle is), there's not a big enough difference to conclusively commend one over the other as a stop gap while you save up for a safe fork.
