If using Shimano cup/cone hubs, be sure that they are adjusted after installation using such high-tension QR levers, as the axle compresses measurably in response to the thousand pounds or so of compressive force.
On older Shimano hubs, some bearing free-play needs to be adjusted into the axle before installing the wheel.
I had an old Viscount bike with nice, hi-flange QR hubs that oddly used brass toothed locknuts, and I couldn't keep the axle from slipping before I finally replaced the drive-side locknut with a steel one.
Due to today's very light bike weights being effectively overcome by cage spring chain tension, I always advise applying weight to the bike's saddle when flipping the QR lever closed. It's the best way to seat the axle fully in the exact position that gravitational impact forces will eventually try to move it to, so may prevent certain cases of slippage or of a wheel dropping out altogether while riding (something I've seen).
