    If you mean the bleed screw fitting or the blanking cap (there's one or the other on the top of each 'leg', usually), you can simply try gently tightening it up a bit (clockwise) with a spanner.

    If the 'O' ring that seals them is still leaking, you'll need to turn off both valves at the bottom completely, open the bleed screw to remove any pressure (and to check the valves are indeed off), and then unscrew the fitting, get a new 'O' ring, put it on, re-fit the fitting and turn the valves back on.

    If your valves are the type with chromed cylindrical 'knobs' and haven't been turned off for a while, you'll probably then need to make separate post on here about 'repairing leaking towel rail radiator valves' though....

    In my recent experience, the castings are incredibly rubbish on towel rails, with burrs, bumps, and threads nowhere near straight.

    The surface the washer will sit against needs to be smooth. If it's bumpy at all then try cleaning it up with some wet and dry. Then refit a new cap and washer as said. If it's simply not straight, try some LS-X.

    The 1/2” vents and plugs for top of towel rails (and other rads) are inexpensive and would do no harm to also replace them.
