This handy strong double ended spanner in 5mm steel finished in gold passivate for outstanding protection against corrosion is longer and thicker than many alternative double ended spanners. This gives greater leverage and force to undo and tighten compression fittings.
The body will not bend and neither will the jaws widen under pressure as with some thinner spanners. Although designed specifically for radiator valve compression fittings it can be used on virtually all 15mm and 22mm compression fitting and nuts.
very useful tool for your tool kit where the gold colouration makes it easy to spot amongst the rest.
