Cross Key Wrench for Radiator Valves & Lockshields

A cross key wrench for radiator valves and lockshields, used across plumbing and sanitary fitting work where several common fixing types need to be handled with one tool. Its multi-function layout makes it useful for working on valve extensions, hanger bolts, vanity fittings and tube plugs without reaching for separate keys.

Used for plumbing repairs, bathroom fitting work and heating system maintenance, this type of wrench suits installers, maintenance engineers, landlords and DIY users carrying out radiator or sanitary jobs at home or on site. It is particularly handy when fitting or removing vanity fixtures, adjusting radiator valve fittings, working on lockshields, or dealing with tube plugs during servicing and repair work.

The wrench combines several working profiles in one cross-shaped tool. External hexagon sizes of 3/8in, 1/2in, 3/4in and 1in are provided for valve extensions on radiator valves and lockshields. Internal threads in M6, M8, M10 and M12 cover hanger bolts used when installing and removing vanity fixtures, while the inner square fits 3/8in and 1/2in tube plugs. The cross form gives a straightforward handhold when turning fittings, and the range of profiles helps cover common plumbing and sanitary tasks without swapping between multiple small specialist tools.
