Radiator Bleed Keys

We have a selection of keys for bleeding air from radiators : clock, brass, alloy and rear access types.
Most UK radiator air vent valve bleed screws have the same size square end - approx 5mm x 5mm - which is the size our keys fit.
Helpful hint : it's best to bleed radiators when the heating system is not operating.
