Raditor knob needed for 7mm square shank

[dal5band]

My bathroom rail/radiator has a larger valve with a 7mm square shank. The plastic knob disintegrated years ago - anybody come accross a valve knob with a 7mm square drive ?

Any chance of a pic of the rad /valve

It's normally quicker cheaper and easier just to change the entire valve

Here are pics of the valve and knob. The union to the radiator is bigger than normal and the pipe is 22mm or the old imperial equivalent. It is gravity fed off the HW primary so we need to turn it offin the summer.

This should fit , just don't look at the cost !
Struggling to find just the knob though

Not sure if that will fit , but it is for a square spindle

Thanks all ! I'll carry on using a spanner for now until the bathroom refurb. The valve has a proper gland so does not leak so no problem.

One of these might be easier than a spanner, think I got mine from Tesco for about £1.
