Essentially yes. The "captive wrench" arm meshes with the tightening nut and is spring loaded so it can be rotated to the desired point for engagement. The 10mm RWS thru bolt skewer is for 135mm drop outs only and requires the correct axle end caps on your hub. I use these skewers on the rear hub for both of my MTB bikes. I also have the road bike versions on one of my wheelsets and they work well but are not particularly light.
