The skewer diameter is universal but the rod length will vary. Front wheel skewers are sized for a 100 mm OLD hub plus dropout thickness and aren't long enough for rear wheel use.
Rear wheel skewers are currently made for 130 mm (road) or 135 mm (MTB) hubs but the MTB skewers are usually threaded far enough down to fit both hub widths. You probably need a skewer long enough for 135 mm dropout spacing.
