It is absolutely necessary to put a lockring on a track hub. A track hub lockring has left-handed threads and fits on smaller diameter part of the threaded portion of a track hub. The lockring goes on after the track cog and keeps the cog in place when backpedaling to slow or stop a fixed-gear bike. As Sheldon Brown noted, if the sprocket starts to unscrew, it should turn the left-hand-threaded lockring, tightening the lock ring.

If you do not have the tools to properly tighten your lockring, please have a professional do this for you. A track cog coming off while riding can be catastrophic.

Here's a double-sided rear track hub showing the stepped-down smaller diameter threaded portion that accepts the lockring.

Our lock rings are 1.29" x 24 TPI, left-hand and will fit most hubs except Campagnolo & Phil Wood (they are 1.32" x 24 TPI, left-hand) and of course, French-threaded track hubs.
